+ * The function adds a constant and an array defined as a sub-matrix with padding

+ * The implementation uses ANSI C and could be compiled and run on any platform

+ * @param[out] output: output array
+ * @param[in]  C: constant value
+ * @param[in]  rows: matrix rows
+ * @param[in]  cols: matrix cols
+ * @param[in]  padd_in: input array padding
+ * @param[in]  padd_out: output array padding
+ * @param[in]  step_in: step over input array (by default should be 1)
+ * @param[in]  step_out: step over output array (by default should be 1)

+ * @return
