How do I use regexprep to replace final NaN values in a matrix?

I have a numeric data stream like this:
NaN NaN NaN 100 102 101 99 102 NaN NaN NaN NaN NaN 101 103 NaN NaN, etc
I'd like to replace the last NaN in each string of NaNs with a zero so it would look like this:
NaN NaN 0 100 102 101 99 102 NaN NaN NaN NaN 0 101 103 NaN NaN
Is this a good regexprep situation or should I do find()?

A=[NaN NaN NaN 100 102 101 99 102 NaN NaN NaN NaN NaN 101 103 NaN NaN]
A(diff(isnan([A 0]))==-1)=0

A = [NaN NaN NaN 100 102 101 99 102 NaN NaN NaN NaN NaN 101 103 NaN NaN];
A(strfind(isnan(A), [true, false]) = 0;
