Detailed Description

Absolute minimum functions compare the absolute values in a vector and return the minimum one along with its index.

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