integer parameters to C MEX s function
显示 更早的评论
function mxGetPr(ssGetSFcnParam(S,0)) can get REAL parameter from the mask of simulink block. is there any function can get integer paramter from simulink block mask, or how to convert a real number to integer in C MEX s function.
Thanks a lot.

I think you need to use mxGetData(ssGetSFcnParam(S,0)) instead and cast the returned void-pointer to an int pointer. You probably want to throw an error if ssGetDTypeIdFromMxArray(ssGetSFcnParam(S,0))!=SS_INT32 (or SS_INT8, SS_UINT8, SS_INT16, SS_UINT16, SS_UINT32 depending on what type you're expecting).
mxGetPr must only be used if the parameter is a double value.

Yes, see http://www.mathworks.com/help/releases/R2011b/toolbox/simulink/sfg/f9-5492.html for SimStruct-specific functions, and http://www.mathworks.com/help/releases/R2011b/techdoc/apiref/bqoqnz0.html#bqoqobe-1 for mxArray related functions.
