Hi !!! Have a nice day.

I have a code that starts with the generation of a matrix A,

after a numerical process at the end I have a matrix B

A = [a, b, c,… ..

q, w, r,….];

instructions

B = [d, e, f,….

and, u, I, ...];

At the end of the numerical process I have matrix B, immediately

the values of B are assigned to A in this way

A = B

What instruction I need to do to generate this cycle N times, that this; the results of B introduce them to input A?

I hope you understand what I want to do

Thank you

No, I don't want to concatenate. I want to update the values of A with the resulting matrix B, in each cycle(n times). But this I have not been able to achieve.

" I want to update the values of A with the resulting matrix B"

So you want to completely overwrite A with whatever is stored in B on each iteration.

But this I have not been able to achieve"

Why not? What specific problems have you faced?

Again, a simple example of expected input and outputs usually saves quite a bit of time and dialog.

You are right.

I should check my code.

Thank you very much for your patience and your help.

Can you show your code? Make sure you are initally setting A before the for loop. If I am understanding the problem, it should look something like this:

A = [a,b,c;q,w,r];
for n = 1:5
    % instructions
    
    % instructions
    
    % instructions
    
    B = [d,e,f;l,m,n]
    A = B;    
end

Is variable A part of the input into building variable B? There must be an error in your code, I do not know how to troubleshoot without code.

Thank you very much.

You are right there must be some error in my code.

Thank you for your patience and attention.
