Hello, I find GSL comes with test code for most of its provided functionalities. In particular, a file called "test.c" can be found in almost all subdirectories, such as FFT (fast Fourier transform) and Cheb (Chebyshev Approximation). But I do not find test code in BLAS (Linear Programming Support). Since BLAS is important in many calculations, perhaps its test code is placed somewhere else in the GSL repository. Can someone let me know where I can find it? Thanks. Zhoulai
