Remove Entire Column when a condition is met.

Hello, I am constructing a cost matrix for an association problem. It is a minimization problem and the cost matrix is structured in this way

C=[12 inf 13 inf inf inf inf;

13 inf 15 inf inf inf inf;

inf inf inf 14 inf 27 inf]

The aim for me is to remove the column in which I have inf elements only i.e. in this example i want to remove 2nd, 5th and 7th column from the cost matrix.

Thanks in advance for the help.

Thank you very much for the reply, this i figured given some answers for the row cases in this forum, but i am not sure on how to define the condition here, i mean, condition such that all the elements are infinite....

I was able to solve the issue by using the code segment shown below.

                    remove=true(size(C,2),1);
                    for pp=1:size(C,2)
                        qq=1;
                        while C(qq,pp)==inf
                            qq=qq+1;
                            if qq==size(C,1)+1
                               remove(pp)=0;
                               break
                            end 
                        end   
                    end 
                   C=C(:,remove)
