Dear all,

I have a set of 4 matrices and i want to create multiple matrices by taking respetive column entries from these 4 matrices. For example,

matrix 1 = [first column A first colum B first column C First column D]

.............

.........

matrix n 0 [nth column A nth column B nth column C nth column D]

Many thanks for your suggestions

i am now using following code but i am only getting the last combination repeated in all cells. Perhaps osmebody can point out the error?

[x y] = size(Temp); %where Temp is one of the four matrices
t = cell(y,1)
for k = 1:y
    t{k}= [Temp(:,[k])  strain_rate(:,[k])  strain_y(:,[k])  stress(:,[k])];
end;

Once I tried to repoduce simmilar case, I did not find any issue

A=randi(10,[5,4]);
B=randi(10,[5,4]);
C=randi(10,[5,4]);
D=randi(10,[5,4]);
Mat=cell(1,size(A,2));
for i=1:size(A,2)
    Mat{i}=[A(:,i),B(:,i),C(:,1),D(:,i)];
end
