DESCRIPTION

74       Each of these functions computes the average of the first source matrix
75       and  the  second source matrix and writes the output to the destination
76       matrix.
77
78
79       It uses the following equation:
80
81         z[i] = (x[i] + y[i] + 1) / 2
82
83
84
85       where i = 0, 1, ..., (m*n - 1) for real data; i = 0, 1, ...,  (m*n*2  -
86       1) for complex data.
87

PARAMETERS

89       Each of the functions takes the following arguments:
90
91       z    Pointer to the destination matrix.
92
93
94       x    Pointer to the first source matrix.
95
96
97       y    Pointer to the second source matrix.
98
99
100       m    Number of rows in the matrices.
101
102
103       n    Number of columns in the matrices.
104
105

RETURN VALUES

107       Each  of the functions returns MLIB_SUCCESS if successful. Otherwise it
108       returns MLIB_FAILURE.
