MATLAB: Ignore Inf in matrix summation

Question

I have a vector

 col_min= [1;0;0;0;0;Inf]

where i want to find the sum, ignoring the inf. So the easy answer should be just 1.

Is it possible to achieve in a simple code? Otherwise, I guess, I have to change the Inf into NaN.

Thanks in advance,

Jonas

Answer 1

index=col_min==Inf;
sum(col_min(index==0))
