1 00:00:01,580 --> 00:00:04,520 Waterfall the mattresses in the mattresses. 2 00:00:04,560 --> 00:00:15,000 You will just right it is equal to one with space to semicolon three with space for one two means that 3 00:00:15,420 --> 00:00:23,040 one and two are to increase in the first floor and 3 and 4 are two injuries in the second row similar 4 00:00:23,070 --> 00:00:31,960 Libby's equal to 4 5 4 5 means that in the second matrix which is to be matrix 45 is the first rule 5 00:00:32,430 --> 00:00:34,980 and 5 7 is the second trial. 6 00:00:35,160 --> 00:00:37,230 Okay valuable right. 7 00:00:37,230 --> 00:00:39,510 A plus B and best intermittent. 8 00:00:39,870 --> 00:00:41,750 You will find the answer. 9 00:00:42,060 --> 00:00:42,360 Okay. 10 00:00:42,390 --> 00:00:47,220 Just like one plus four Two plus five plus five four plus seven. 11 00:00:47,310 --> 00:00:49,860 You will get automatically the answer in the matlab. 12 00:00:50,420 --> 00:00:51,190 Okay. 13 00:00:51,670 --> 00:00:53,470 So A minus B means. 14 00:00:53,910 --> 00:00:58,740 It is a subtraction and aesthetic B means that this is multiplication. 15 00:00:58,920 --> 00:01:06,520 And here a prime means that this is transpose when you work type it airplane and pass the intermittent. 16 00:01:06,570 --> 00:01:16,050 It means that you are getting transpose okay off Mattox a mistake when you're type bean bean the inside 17 00:01:16,050 --> 00:01:16,890 of the bracket. 18 00:01:16,950 --> 00:01:20,710 E Just like R B involves being worse off. 19 00:01:21,120 --> 00:01:28,770 Which means that you're finding that in what sort of matters E and F will be written inside the backwards 20 00:01:36,390 --> 00:01:39,300 even Middleton in the parenthesis 21 00:01:43,770 --> 00:01:54,460 no take some example to understand discord in match lap the Murdochs e will be written as dislike is 22 00:01:54,460 --> 00:02:03,440 equal to inside the square brackets we will write a slate one two three and with the semicolons four 23 00:02:03,450 --> 00:02:05,080 five six in the first row. 24 00:02:05,080 --> 00:02:11,980 We have written one two three and in the second drill four five six and a third rule is seven eight 25 00:02:12,610 --> 00:02:12,970 nine. 26 00:02:13,810 --> 00:02:19,150 Okay so this is the mechanics e after passing the interval of antibiotics. 27 00:02:19,150 --> 00:02:28,720 Yes and in the second matrix the matrix B is one two three. 28 00:02:28,750 --> 00:02:32,630 Okay in the first drawer and we will separate it. 29 00:02:32,890 --> 00:02:37,970 Every rule will be separated by the semicolons and the second row is four five six. 30 00:02:38,050 --> 00:02:45,400 The third rule is just like six five seven after besting the interpreter of the epidemic to speak. 31 00:02:45,400 --> 00:02:51,580 So eight plus me is equal to this matrix just like you will write in the MATLAB a plus b you will get 32 00:02:51,580 --> 00:02:52,750 the answer. 33 00:02:52,860 --> 00:02:59,950 And similarly e minus B means that you are subtracting metric C and B and E started to be means that 34 00:03:00,370 --> 00:03:02,780 you are multiplying matrix A and B. 35 00:03:02,860 --> 00:03:05,380 And this is your answer. 36 00:03:06,100 --> 00:03:06,760 Okay. 37 00:03:07,170 --> 00:03:11,130 So no E prime. 38 00:03:11,260 --> 00:03:20,710 It means that this or that transpose transpose of metrics e and similarly B I means that transpose off 39 00:03:20,710 --> 00:03:21,820 matrix me. 40 00:03:21,910 --> 00:03:23,990 So this is the transpose up that matters B. 41 00:03:25,200 --> 00:03:25,810 Yes. 42 00:03:25,870 --> 00:03:26,510 No. 43 00:03:26,560 --> 00:03:34,540 We can see that this like e was. 44 00:03:34,660 --> 00:03:36,110 Yes. 45 00:03:36,220 --> 00:03:38,280 So this is the inverse okay. 46 00:03:39,040 --> 00:03:44,500 Oh well again take some matrix yes. 47 00:03:44,760 --> 00:03:45,660 Okay. 48 00:03:45,760 --> 00:03:46,730 All that matters. 49 00:03:46,800 --> 00:03:48,300 E d. 50 00:03:48,300 --> 00:03:55,650 D One two three four five seven. 51 00:03:55,900 --> 00:04:00,810 And it is the first choice for 5 7 and the second row is 6 7 8. 52 00:04:01,120 --> 00:04:11,420 And the third rule is it is just like yes we are taking four by four matters. 53 00:04:11,700 --> 00:04:20,720 We are including one element more so the second rule is 6 7 8 6 9 3 4 6 the first row is 4 5 7 6. 54 00:04:21,130 --> 00:04:27,820 The last voice 9 3 4 6 and uh the last row is 7 5 4 3 or so. 55 00:04:28,900 --> 00:04:32,260 So this is the matrix of the best of the enter button. 56 00:04:32,260 --> 00:04:47,130 Now we will take the other matrix whose first draw is this like 1 3 4 2 3 and the second rule is it 57 00:04:47,140 --> 00:04:49,450 is 4 5 6 5. 58 00:04:50,260 --> 00:04:52,570 And the third rule is 59 00:04:56,690 --> 00:04:59,510 it is 9 8 6 4 2. 60 00:04:59,900 --> 00:05:04,390 And the last 4 E's 61 00:05:06,980 --> 00:05:10,250 4 0 3 5. 62 00:05:10,650 --> 00:05:14,200 After pressing that internal button we will get them out. 63 00:05:14,200 --> 00:05:18,630 Trust me or there is some thing which is wrong. 64 00:05:19,300 --> 00:05:22,020 So what is strong. 65 00:05:22,400 --> 00:05:23,050 Here. 66 00:05:23,390 --> 00:05:23,730 Okay. 67 00:05:23,740 --> 00:05:29,300 It means that we write it again okay. 68 00:05:29,420 --> 00:05:34,700 I thing uh the space to the space. 69 00:05:35,420 --> 00:05:36,420 Yes. 70 00:05:36,530 --> 00:05:37,980 OK we'll write it again. 71 00:05:38,000 --> 00:05:47,170 It is just like 1 3 4 2 1 2 3 4 5 6 in the second trial 72 00:05:52,380 --> 00:05:57,100 in the second drawer and in the third row right. 73 00:05:57,180 --> 00:06:04,030 9 8 6 4 and the last race 4 0 3 5. 74 00:06:05,190 --> 00:06:17,490 Yes this is the right to speak and to know will add this matrix A plus B which is equal to these metrics 75 00:06:18,120 --> 00:06:26,490 and e minus B means we are subtracting a and b with metric C is what a simple operations used in MATLAB 76 00:06:26,520 --> 00:06:36,520 so it transpose is equal to this matrix and b transpose is equal to this matrix is very simple. 77 00:06:36,570 --> 00:06:47,010 Okay so a transpose plus b transpose we are adding a transpose and b transpose we'll get that matrix. 78 00:06:47,340 --> 00:06:47,830 Yes. 79 00:06:48,240 --> 00:07:01,140 So no it transpose minus B transpose which is equal to the metrics and uh a star B means we are multiplying 80 00:07:01,140 --> 00:07:03,380 matters and B we'll get this on set. 81 00:07:03,420 --> 00:07:03,890 Okay. 82 00:07:03,930 --> 00:07:05,750 And no. 83 00:07:06,450 --> 00:07:07,590 Well yes 84 00:07:10,820 --> 00:07:20,180 a store B means multiplication of the and B R is tough. 85 00:07:20,690 --> 00:07:22,520 Yes. 86 00:07:22,680 --> 00:07:23,930 Is to be 87 00:07:27,160 --> 00:07:29,740 a key B transpose. 88 00:07:29,770 --> 00:07:30,250 Yes. 89 00:07:30,250 --> 00:07:38,410 E or b transfer mean we are multiplying Metro C and we trust means transport lobby and it transpose 90 00:07:38,410 --> 00:07:39,850 multiplied by B. 91 00:07:39,850 --> 00:07:40,940 Is this match x. 92 00:07:41,190 --> 00:07:46,720 Okay so these are very simple operations used in Matlab. 93 00:07:46,720 --> 00:07:49,110 You can find the answer in minutes. 94 00:07:49,450 --> 00:07:49,990 Okay. 95 00:07:50,140 --> 00:07:51,980 Not in minutes district seconds. 96 00:07:52,010 --> 00:07:59,570 OK so you are seeing or hear that now we are finding that it was B in Warsaw. 97 00:07:59,590 --> 00:08:01,530 We will get this metrics. 98 00:08:01,570 --> 00:08:08,250 So this is the inverse of metric C and B in was off B. 99 00:08:08,920 --> 00:08:09,400 OK. 100 00:08:09,460 --> 00:08:20,860 After passing the interpreter you will get up in oneself Mattox me and uh Mo. 101 00:08:21,690 --> 00:08:26,100 B In was R E 102 00:08:29,030 --> 00:08:37,030 yes multiplied by B in was R B means we are multiplying two and worse and worse off here in Warsaw. 103 00:08:37,040 --> 00:08:40,840 B So we'll get this matter such replacing the enter button. 104 00:08:41,260 --> 00:08:43,890 Okay. 105 00:08:44,710 --> 00:08:45,640 Yes. 106 00:08:45,710 --> 00:08:51,010 Now it is yes. 107 00:08:51,020 --> 00:08:52,610 So these are the operations. 108 00:08:52,820 --> 00:08:55,380 What are simple operations what a simple code. 109 00:08:55,460 --> 00:08:56,720 It is not a difficult call. 110 00:08:56,720 --> 00:09:02,700 So you can use these called for any calculations electrical matters. 111 00:09:02,770 --> 00:09:03,130 Okay. 112 00:09:03,200 --> 00:09:03,830 In matlab.
