Simplify array indexing

Replace multiply operations in array indices when accessing arrays in a loop.

Category: Optimization

Default: Off

On: In array indices, replace multiply operations with add operations when accessing arrays in a loop in the generated code. When the original signal is multidimensional, the Embedded Coder^® generates one-dimensional arrays, resulting in multiply operations in the array indices. Using this setting eliminates costly multiply operations when accessing arrays in a loop in the C/C++ program. This optimization (commonly referred to as strength reduction) is particularly useful if the C/C++ compiler on the target platform does not have similar functionality. The absence of multiply operations in the C/C++ program does not imply that the C/C++ compiler does not generate multiply instructions.
Off: Leave multiply operations in array indices when accessing arrays in a loop.
