Detailed Description

Elementwise clipping functions constrain values from elements of a source vector to be within two bounds and write the results one-by-one into a destination vector.

Terapines DSP library supports distinct elementwise clipping functions for single-precision floating-point, Q31, Q15 and Q7 data types. These functions are introduced in the subsections below.
