DESCRIPTION

84       Each of these functions performs an in-place multiplication of two vec‐
85       tors and shifts the result.
86
87
88       For real data, the following equation is used:
89
90         xz[i] = xz[i] * y[i] * 2**(-shift)
91
92
93
94       where i = 0, 1, ..., (n - 1).
95
96
97       For complex data, the following equation is used:
98
99         tmp         = xz[2*i]
100         xz[2*i]     = (tmp*y[2*i] - xz[2*i + 1]*y[2*i + 1]) * 2**(-shift)
101         xz[2*i + 1] = (tmp*y[2*i + 1] + xz[2*i + 1]*y[2*i]) * 2**(-shift)
102
103
104
105       where i = 0, 1, ..., (n - 1).
106

PARAMETERS

108       Each of the functions takes the following arguments:
109
110       xz       Pointer  to  the  first element of the first source and result
111                vector.
112
113
114       y        Pointer to the first element of the second source vector.
115
116
117       n        Number of elements in each vector.
118
119
120       shift    Right shifting factor. The ranges of valid shift are:
121
122                  1 ≤ shift ≤ 8   for U8, S8, U8C, S8C types
123                  1 ≤ shift ≤ 16  for S16, S16C types
124                  1 ≤ shift ≤ 31  for S32, S32C types
125
126
127

RETURN VALUES

129       Each of the functions returns MLIB_SUCCESS if successful. Otherwise  it
130       returns MLIB_FAILURE.
