How can i convert a C++ mex file for matlab function to VHDL code implemented on FPGA.?

Hi WHech,

You may use the Intel HLS Compiler that synthesizes a C++ function into an RTL implementation that is optimized for Intel FPGA products.

Kindly refer to https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/hls/ug-hls-getting-started.pdf for details.

Thanks.
