Hi,

I have very simple question but couldn't find a simple answer to it:

how can i get ith row or column of a matrix acc.to given dimension value. I mean, i need such a function:

v=getroworcolumnvector(Amatrix,i,dim);

for Amatrix is 2 dimensional array, it should give a vector which is ith row of Amatrix if dim==1, or ith column of Amatrix if dim==2

Thank you,

Baris

c = repmat({':'},1,ndims(A));
c{dim}=i;
A(c{:})
