how do i write a function that splits a 16x1 matrix into a 4x4 matrix

Answer 1

[Image Analyst]

out4x4 = reshape(vector16x1, [4, 4])

Answer 2

[Youssef Khmou]

Use reshape as mentioned by @Image Analyst , or use standard method :

 function Y=split16144(X)
 Y=zeros(4,4);
 ctr=1;
 for x=1:4
    for y=1:4
        Y(x,y)=X(ctr);
        ctr=ctr+1;
    end
 end

Equivalent to

reshape(vector16x1, [4, 4]).'
