MATLAB: Removing components of a matrix without turning it into a vector

Question

Hello I'm trying to remove the Inf values from my matrix Z without turning it into a vector. I have an idea of how to do it using loops, and I know Z(1,:)=[] + Z(:,4)=[] will work as I want it to but I wanted to see if there's a quicker way because it seems like this should be a trivial thing for MATLAB. Z is actually a sample matrix, the matrix I am working with is larger and within a function, so the Inf locations will always be different.

Thanks!

Z =
     Inf   Inf   Inf   Inf
       4     6    13   Inf
      10    12    19   Inf
      11    18    25   Inf
  >> Z(Z==Inf)=[]
  Z =
       4    10    11     6    12    18    13    19    25

Answer 1

ii = isinf(Z);
out = Z(~all(ii,2),~all(ii));

or

ii = ~isinf(Z);
out = reshape(Z(ii),max(sum(ii)),[]);
