Blitz++ can indeed help you to multiply matrices. Elementwise multiplication is done by default for a*b where a and b are matrices. See also docs for the product() function (sec. 3.13) and for index placeholders which may be used to perform an outer product of two arrays (sec. 3.11): http://blitz.sourceforge.net/resources/blitz0.9.pdf HTH, Sylwester  http://www.igf.fuw.edu.pl/~slayoo/
