Function GFLIB_Lut2D_F32
data outside the provided data table, then the interpolation will
be computed with invalid data.
4.69.5 Re-entrancy
The function is re-entrant.
4.69.6 Code Example
#include "gflib.h"
tFloat fltIn;
tFloat fltOut;
GFLIB_LUT1D_T_FLT trfltMyLut1D = GFLIB_LUT1D_DEFAULT_FLT;
tFloat pfltTable1D[9] = {-1,0,-0.2,0,0.2,0,0.8,1,1};
void main(void)
{
// setting parameters for Lut1D function
trfltMyLut1D.pfltTable = &(pfltTable1D[4]);
trfltMyLut1D.s32ShamOffset = 2;
// input vector = 0.5
fltIn = 0.5;
}
// output should be 0.8
fltOut = GFLIB_Lut1D_FLT (fltIn,&trfltMyLut1D);
// output should be 0.8
fltOut = GFLIB_Lut1D (fltIn,&trfltMyLut1D,Define FLT);
