print value to matrix

Hello everyone,

I have a code.In this code, there are V values ​​consisting of 20 rows as a result of each iteration.What I want to do: I want to see the v values ​​formed in each iteration in the same matrix. How can I do it?

for example;

iteration:1

V=

10

5

1

....

iteration:2

V=

15

4

2

....

V_new;

iteration 1 2 3 4 ....

10 15 20 10

5 4 3 2

1 2 3 8

thanks advance

nIter=YourNumberOfTotalIterations;
nRows=20;
V=zeros(nRows,nIter);               % preallocate
for i=1:nIter
   V(:,i)=YourFunctionCreatingVector(...);
end

[Voss]

V_new = [];
for ii = 1:max_iterations
    % calculate V
    V_new(:,ii) = V;
end

Also, if you know ahead of time how many iterations there will be, you can preallocate V_new to be the appropriate size before the loop:

V_new = zeros(20,max_iterations);
