/** @brief Sligtly less accurate version of F0-transfrom computation optimized for higher speed. The methods counts with linear basic function.
@param matrix Input 3 channels matrix.
@param radius Radius of the **LINEAR** basic function.
@param output Output array.
This function computes F-transfrom and inverse F-transfotm using linear basic function in one step. It is ~10 times faster than **FT02D_process** method.
