Matlab to C code conversion

Hi, I would like to convert a Matlab code to C code. My code supposed to make correction (in video) by Affine transform in the location of ROI that carried out in him a displacement and rotation. I used in "coder.screener" for checking which functions can't be converted to C and the coder found that there are 2 function which not supported for this conversion: 1. cvexEstStabilizationTform. 2. cvexTformToSRT. Are there other functions that replace them and supported in C conversion? Thanks, Itai
