195 * This set of functions provides basic matrix math operations.
196 * The functions operate on matrix data structures. For example,
198 * definition for the floating-point matrix structure is shown
203 * uint16_t numRows; // number of rows of the matrix.
204 * uint16_t numCols; // number of columns of the matrix.
205 * float32_t *pData; // points to the data of the matrix.
210 * The structure specifies the size of the matrix and then points to
213 * matrix element (i, j) is stored at:
219 * There is an associated initialization function for each type of matrix
240 * By default all of the matrix functions perform size checking on the input and
241 * output matrices. For example, the matrix addition function verifies that the
242 * two input matrices and the output matrix all have the same number of rows and
251 * There is some overhead associated with this matrix size checking.
252 * The matrix size checking is enabled via the \#define
