I have an array A of 7 dimensions, and a vector v of length 5.
I need to select a subset of A where the first five coordinates are the ones specified by V. I can accomplish this by:
A(v(1), v(2), v(3), v(4), v(5), :, :)
but it wont work if the length of v changes from one application to another. Is there any way straight forward way to go about this?
Thanks!!!

idx=repmat({':'},1,ndims(A));
idx(1:numel(v))=num2cell(v);
result=A(idx{:});
