[hpsdr] Interesting Math Library with 4x performance increase

[Gregory W. Ratcliff]

Warren, 
Yes, and  as I read the documentation today:
   
   - Matrix functions
   
   - This category includes test for computations that heavily involves matrix manipulation, e.g. fast fourier transforms, computing eigen values and the matrix inverse.
 I think most recently you were exploring matrix inverses.  
Thank you,
Greg

 Hi Greg, The only math library, other than what openHPSDR developers have written, that we're using today for PowerSDR and follow-ons, if the FFTW library for FFTs  (it's VERY good by the way, FFTs seem almost free).  In WDSP, I've written and included various matrix inversion algorithms and other things as needed.  The issues with the Intel libraries in the past have been licensing.  I think, over the years, they've softened their stance, somewhat at least, on that.  It deserves a closer look.  The benchmark for "Singular Value Decomposition" caught my eye ... I have something in mind for that and haven't had time to write the code myself.:-) 73, Warren  NR0V

  I took the appliance operator path and installed binaries before I went digging into source and the API.
