Squeeze Some of Singleton Dimensions in Matlab

How can I squeeze only a subset of singleton dimensions of a matrix in Matlab? The squeeze function removes them all.

I keep the index to those dimensions in a vector called "dims".

Solution

  • Code

    %// Input matrix is assumed as A
sz = size(A)
t2 = sz~=1
t2(dims)=1
out = reshape(A,sz(t2)) %// out is the desired output

    If you are crazy about dense codes, you can try this -

    sz = size(A)
out = reshape(A,sz(sort([dims find(sz~=1)])))
