I did not notice at the time of the original post that you were not asking for the maximum over the entire matrix. I later updated with "there are no LAPACK or BLAS calls for scalar multiplication or division on a per-column basis."

Is there a LAPACK or CBLAS function that can be used to normalise
an m by n matrix ?
A=abs(B/max(B)); %B is m by n matrix
No, there is no LABACK or CBLAS function for this. Do you mean
A = abs(B / max(B(:))) % The (:) is essential
% Or
A = abs(B ./ max(B)) % The ./ is essential
Is there a LAPACK or CBLAS function that can be used to
find log10 of an m by n matrix?
A = 10*log10(B);
No, there is no LAPACK or BLAS function for this. The shown code is efficient already.

I do not see any routines for element by element multiplication. http://www.icl.utk.edu/~mgates3/docs/lapack.html
