Overview

Copies the column data pointed to by Index to the output wire

Discussion

This module maintains a user configurable 2D array (table) of user data (int, float, Fract32). At the input pin it accepts an integer index that is used as a column index selector of the table. All the elements of the selected column are then output at the output wire.

The column selector index is zero-based and will be internally limited to the allowable range of the table. If input index is less than zero, then the first column will be selected. If index is greater than numCols, then the last column will be selected. Only the first element of the input pin is considered as the column selector. All other values are ignored.

    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 index;                                  // current column index into the multi-dimensional array
    INT32 numRows;                                // the size of each vector
    INT32 numCols;                                // the number of vectors
    FLOAT32* coeff;                               // 2-D table.
