I am looking to transition some of my MATLAB algorithms to C/C++ for deployment on target (PowerPC and/or ARM). Mostly 1D FIR/IIR filter in this instance.
In other domains, there are well-regarded general libraries (both speed and quality) with liberal licencing. For example, Linear Algebra has LAPACK and Eigen (amongst others), and computer vision has OpenCV.
There are well-regarded libraries for specific algorithms, such as FFTW, but what about a collection of general algorithms for 1D signals?
