Hi, I am about to push in SVN the first version of a small package to compute lpc coefficients and lpc residual. I spent most of the time trying to understand how to handle non contiguous arrays in various parts of the C code... Now, I am wondering: does it really worth the trouble ? I noticed that most of the time, it is even faster (and obviously much easier to code/debug/test, and much more reliable) to just copy the data in a contiguous new array before processing with a C function expecting contiguous array... Is there a general policy regarding thoses issues for scipy ? Is it enough to write simple C extensions expecting contiguous arrays, and converting input to contiguous layout if necessary ? Cheers, David
