This screencasts gives an example of a nested FOR loop in a MATLAB program and how to create it based on a written algorithm. Also introduces the SIZE and MOD commands as a side trip.

what does mod do??

Hi, -74% coupon to Learn Matlab course

Sir, please tell me about loops that are used to take two inputs simultaneously and computing it: example-

fori=1:5

forj=1:5

fprintf(‘n take length 1:’);

fprintf(‘n take length 2:’)

%other computations

end

end

good job but speaking slower would make it easier to follow

I am about to lose my mind right now

I’ve been trying for 4 hours to create a matrix with nested for loops

the matrix should have the output

1 2 3 4 5 6

1 2 3 4 5 6

1 2 3 4 5 6

Basically repeating a row n times, I am going crazy with these nested loops since I have to create a 50×50 matrix using that method in which element (1,1) is -5 and element(1,50) is -5, so

-5 -4.8 -4.6 …………

-5 -4.8 -4.6 …………

-5 -4.8 -4.6 …………

-5 -4.8 -4.6 …………

My code is as follows:

x(1,1) = -5;

%Loop to create the x matrix

for i = 1:50

for j = 1:50

x(i+1,j) = x(i,j) + 0.2;

x(i+1,j) = x(i,j);

end

end

This constantly gives be a 2×1 matrix. What is going on, I don’t see ANYTHING wrong with this code

Please help, I am about to go insane

thank you so much

is it possible to save the resulting variables during the loop operation. for example for a loop from 1:5, i want to save all the generated variables during the iteration cycle under a different name. can it be done?

I am an absolute beginner in programming and I find this video very useful! Thank you very much!

supercool,you are my hero…btw is it macbook or mac book pro..???

k=1;

for j= 2:2:rlen2r

rl(j,:)=rf2ll(k,:);

rh(j,:)=rf2hl(k,:);

k=k+1;

end

for this code what is the value of this ” : ” , (k,:) Please give me details “?

say within a for loop defined as,

i=1:100

if …..

elseif…..

while…..

If I have a condition in the while loop that terminates the current history it is on and goes to the next history within the for loop… How would I do that? Say the condition is met in i=1, I want to terminate that loop if the neutron is lost and start, i=2.

Please help…

Thank you!

Hi there. there is more than one way.

– [1 2 3;4 5 6;7 8 9] each “;” starts a new row, so this end up being a (3*3) matrix.

– or use: a:b:c where a is your initial value, b is your step size, c is your final value.

– or use the command : magic(A) , if A=3 you end up having a 3*3 matrix and so on.

I hope this helps.

Thank you for not having an accent

Hello, i have wind speed data(per second) and i need a loop to calculate the average every 1 minute(60sec). 5.270.341rows 1column. Can you help me?

your tutorial videos are really helpful and precise,keep up the good work!!

what is the difference between using MOD and REM commands?

that was a great lesson from you and I admired you way of explaining the example, I am welling to have a chat with you about somthing that I need the help in it. Welling to have you answer soon

Thank you in advance

Just curious how to use MATLAB to find the values of a symbol?

Giving a+c=30 and 2<= c-a<=10 Both a and c are within a function and I need to find the min and max values of a? Any help would be greatly appreciated

nice!

hello sir, can you help me to complete my thesis?

Shouldn’t num_rows=size(A,2)?? Because the output of the function gives you the number of rows.

How can a user enter an array of his own choice??What is the command for that? please answer

MOD function is almost like rem Function which also calculates remainder I guess.

I found this very helpful, but I felt that there were a few commands that were used but not fully explained:

“fprintf”, “%0.0f”, and “.n”

I do not know where these came from and what they do (aside from if they are used exactly the same as in this case).

Thanks!

cool !

Molto interessante, suggerisco anche il corso grautito di “Corsi Consulenze NPR”, https://youtu.be/nc1zk0DAJn0

wonderful , great job 🙂

Can you please show how to solve a matrix of a 5×3 and have it in increase in the order of small to large.

Example [ 1 2 5

15 18 23 ]

Thank you.

neat

Very well presented! I wish it were explained this clearly when I was learning it!

Gr8! Was very helpful!

Hi Sir, can you create Matlab program for 2 input and 2 output using if else statement? Thank you very much

fprintf(‘Thank you so much’)

Thank you and +10pts for sounding like an older Sheldon from Big Bang Theory
