How to create a 5D matrix by repeating a 2D array?

Hello everyone,

I'm trying to create a 5D matrix from a 2D array by repeating it for each array in the 5D matrix. I managed to do it using for loop.

A = zeros(1,70); % 2D array
X = zeros(length(N),length(lg),length(C),length(E),length(A)); %% 5D matrix
for p = 1:1:length(A)
    X(:,:,:,:,p)=A(p);
end

Is there any shorter way to do this?

Thanks.

A has 70*70 elements. The loop runs only 70 times.

Anyway, look into repmat(), reshape(),repelem().

I'm sorry, I wrote the code wrong. A is actually 1x70 matrix. I edited it already.

Already tried the functions you mentioned but still I couldnt get the matrix that I wanted.

A=1:5;
X=zeros(2,3,5);

X=reshape(repelem(A,2*3),2,3,[])

Ok thanks, I'll try that.
