SciPy - I need an example of use of linalg.lstsq()

And it has to run on Windows, so it can't use xplt. I would prefer that it use the simplest multi-dimensional model, z = k + a*x1 + b*x2 + c*x3 + d*x4 Anyone have such a thing? Thanks, Mitchell Timin -- I'm proud of http://ANNEvolve.sourceforge.net. If you want to write software, or article

Can Python kill a child process that keeps on running?

Suppose we spawn a child process with Popen. I'm thinking of an executable file, like a compiled C program. Suppose it is supposed to run for one minute, but it just keeps going and going. Does Python have any way to kill it? This is not hypothetical; I'm doing it now, and it's working pretty

How can I implement a timeout with subprocess.Popen()?

I want my Python program to invoke a compiled C program, and capture the text output. Here's a fragment from a program that works, using subprocess.Popen: p = Popen(execName, stdout=PIPE) while(1): line = p.stdout.readline() # get next line outfile.write(line) (The

Why does bufsize=1 not work in subprocess.Popen ?

I read in the docs that "bufsize=1" causes line buffering. (for subprocess.Popen) The following tiny program launches an executable file and then receives its output. That works, but I want to receive each line as it is ouput, not all of the lines at termination, which is what is happening. -

Python used to animate a compiled C program

SailChallenge was originally a program in C. It simulates a sailboat being navigated by an ANN (Artificial Neural Network). Now a Python "front end" has been created which invokes the compiled C program, and then captures the real time text output, converting it into an animation. A screen s
