DESCRIPTION

85       Each  of  these  functions  performs  a multiplication of a vector by a
86       scalar and shifts the result.
87
88
89       For real data, the following equation is used:
90
91         z[i] = x[i] * c[0] * 2**(-shift)
92
93
94
95       where i = 0, 1, ..., (n - 1).
96
97
98       For complex data, the following equation is used:
99
100         z[2*i]     = (x[2*i]*c[0] - x[2*i + 1]*c[1]) * 2**(-shift)
101         z[2*i + 1] = (x[2*i]*c[1] + x[2*i + 1]*c[0]) * 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       z        Pointer to the first element of the result vector.
111
112
113       x        Pointer to the first element of the source vector.
114
115
116       c        Pointer to the source scalar. When the function is  used  with
117                complex data types, c[0] contains the real part of the scalar,
118                and c[1] contains the imaginary part of the scalar.
119
120
121       n        Number of elements in each vector.
122
123
124       shift    Right shifting factor. The ranges of valid shift are:
125
126                  1 ≤ shift ≤ 8   for U8, S8, U8C, S8C types
127                  1 ≤ shift ≤ 16  for S16, S16C types
128                  1 ≤ shift ≤ 31  for S32, S32C types
129
130
131

RETURN VALUES

133       Each of the functions returns MLIB_SUCCESS if successful. Otherwise  it
134       returns MLIB_FAILURE.
