For you c++ experts, how can I code the Discrete Fast Fourier Transform for SC? (I'm not a C++ expert and have probably done several things wrong..but I'm trying!) Attached is my attempt at FFT coded from reference C++ code in listing one: http://www.drdobbs.com/cpp/a-simple-and-efficient-fft-implementatio/199500857 Other options listed in the article look good...I'm just not sure how to code them in SC. Also, there are precompiled dll's but if there are examples of referencing external dll's, if would be helpful. If you know, can you please provide an example? http://www.fftw.org/ Regards |

Here is a version that compiles but it crashes SC when applied. Any ideas? Date Time Of Last Edit: 2014-11-11 17:06:32
