Fixed-Point Matrix Operations in MATLAB

Optimized fixed-point matrix solvers and matrix decomposition functions for efficient code

Use these functions to perform fixed-point math and matrix operations and generate efficient code. These functions solve systems of linear equations and perform matrix decompositions in a way that is efficient for embedded devices.
