Overview
Updates module array from different preset tables.
Discussion
This module updates the array of any other module from the presetsArray. The presetsArray is a 3-D array of numArrays, each with size numRows x numCols. The 3-D array is arranged as cascaded 2-D arrays For example, 3 arrays with size 2 x 3 each is arranged as 0 0 0 0 0 0 1 1 1 1 1 1 2 2 2 2 2 2 where 2x3 array with zeros is one array, 2x3 array with ones is second array and so on. The cascaded 2-D array is multiplied or added element by element to create one 2-D array of size numRows x numCols, which is then used to update the array of the other module. The math operation is controlled by the operation argument, either multiplication or addition.

INT32 numRows; // the number of vectors.
INT32 numCols; // the size of each vector.
INT32 operation; // math operation on presets. 0 - multiplication and 1 - addition.
INT32 initialFlag; // boolean flag which handles initial setup.
FLOAT32* presetsArray; // 3-D presets array table.
void * modPtr; // Points to the module to set.
void * varPtr; // Points to the variable to set within the module instance structure.
