Last time I looked at numpy (for Python3) it was available in source only. I know, real men do compile, but I am an old man... I will compile if it is unavoidable, but in case of numpy it does not seem a simple matter. Am I badly mistaken? euclid has another attraction - the source is readily available, not too burdened by backward compatibility issues and relatively easy to follow, though I "managed" to get lost in it :) OldAl. -- Algis http://akabaila.pcug.org.au/StructuralAnalysis.pdf
