DESCRIPTION

137       Each  of  these  functions  performs matrix multiplication of the first
138       matrix to the second matrix or the first complex matrix to  the  second
139       complex matrix.
140
141
142       For real data, the following equation is used:
143
144                      l-1
145         z[i*n + j] = SUM (x[i*l + k] * y[k*n + j])
146                      k=0
147
148
149
150       where i = 0, 1, ..., (m - 1); j = 0, 1, ..., (n - 1).
151
152
153       For complex data, the following equation is used:
154
155                              l-1
156         z[2*(i*n + j)]     = SUM (xR*yR - xI*yI)
157                              k=0
158
159                              l-1
160         z[2*(i*n + j) + 1] = SUM (xR*yI + xI*yR)
161                              k=0
162
163
164
165       where
166
167         xR = x[2*(i*l + k)]
168         xI = x[2*(i*l + k) + 1]
169         yR = y[2*(k*n + j)]
170         yI = y[2*(k*n + j) + 1]
171         i = 0, 1, ..., (m - 1)
172         j = 0, 1, ..., (n - 1)
173
174

PARAMETERS

176       Each of the functions takes the following arguments:
177
178       z    Pointer to the destination matrix.
179
180
181       x    Pointer to the first source matrix.
182
183
184       y    Pointer to the second source matrix.
185
186
187       m    Number of rows in the first matrix.
188
189
190       l    Number  of  columns in the first matrix, and number of rows in the
191            second matrix.
192
193
194       n    Number of columns in the second matrix.
195
196

RETURN VALUES

198       Each of the functions returns MLIB_SUCCESS if successful. Otherwise  it
199       returns MLIB_FAILURE.
