removing a complex infinity

If I have elements in a matrix which are 0 + Infi, what is the best way to delete these elements?

I have tried

 x(x==0+infi) = [];

but this doesn't seem to work.

kind regards,

Tom

x(real(x)==0&isinf(imag(x))) = [];

Thanks, but this seems to be deleting every element in the matrix...
