I needed to write a sed/awk Python equivalent for walking into a directory tree and renaming certain subdirectories, while also looking into all xml files on the way and replacing/modifying certain strings in those files.It would be nicer if someone could suggest an enhanced re.sub(regex,...

This example will show you how easy it is to draw objects using openGL.It draws a giant pyramid and you can walk around inside this foggy temple. Not much to it but it is suitable to learn from.

Newton number (also called the drag coefficient) and Archimedes number are plotted versus the Reynolds number for the laminar, transition and turbulent flow types using a log-log scale. A numerical example of the terminal fall velocity computation of a single spherical particle in a Newtonian...

This function will return true if the first input structure contains the field in the second input string and in turn that field has the field given in the third input string and so on. This allows A.b.c = 2; to be checked as:isfieldRecursive(A,'b','c')ans =1Which would return false if either b...
