Let's say:
A=[1 2 3 5
2 Inf Inf Inf ---->delete this row
3 1 7 5
9 Inf Inf Inf ---->delete this row
11 3 45 91 ]
Question: If i want to delete the row contain "Inf", how can I do that?
result_A=[1 2 3 5
3 1 7 5
11 3 45 91 ]

[r,c]=find(ismember(A,Inf));
A(r,:)=[]

Here is a way that don't change the original matrix:
B = A(any(~isinf(A),2),:)
