Is it possible that a C-mex s-function outputs single float data ?

It seems that by default the level 2 S-function wrapper uses double float type without any possibility to use single float.

ssSetOutputPortDataType()

Thanks, i will thus use the following :

ssSetInputPortDataType(S, 0, SS_SINGLE);
...
ssSetOutputPortDataType(S, 0, SS_SINGLE);
...
real32_T *u1 = (real32_T *) ssGetInputPortSignal(S, 0);
...
real32_T *y1 = (real32_T *) ssGetOutputPortSignal(S, 0);
...
