.SH DESCRIPTION
.sp
.LP
Each of these functions scales a vector by multiplying by a scalar and adding an offset.
.sp
.LP
For real data, the following equation is used:
.sp
.in +2
.nf
z[i] = a[0]*x[i] + b[0]
.fi
.in -2

.sp
.LP
where \fBi = 0, 1, ..., (n - 1)\fR.
.sp
.LP
For complex data, the following equation is used:
.sp
.in +2
.nf
z[2*i]     = a[0]*x[2*i] - a[1]*x[2*i + 1] + b[0]
z[2*i + 1] = a[1]*x[2*i] + a[0]*x[2*i + 1] + b[1]
.fi
.in -2

.sp
.LP
where \fBi = 0, 1, ..., (n - 1)\fR.
.SH PARAMETERS
.sp
.LP
Each of the functions takes the following arguments:
.sp
.ne 2
.mk
.na
\fB\fIz\fR\fR
.ad
.RS 5n
.rt  
Pointer to the first element of the destination vector.
.RE

.sp
.ne 2
.mk
.na
\fB\fIx\fR\fR
.ad
.RS 5n
.rt  
Pointer to the first element of the source vector.
.RE

.sp
.ne 2
.mk
.na
\fB\fIa\fR\fR
.ad
.RS 5n
.rt  
Pointer to the source scaling factor. When the function is used with complex data types, \fBa[0]\fR contains the real part of the scaling factor, and \fBa[1]\fR contains the imaginary part of the scaling factor.
.RE

.sp
.ne 2
.mk
.na
\fB\fIb\fR\fR
.ad
.RS 5n
.rt  
Pointer to the source offset. When the function is used with complex data types, \fBb[0]\fR contains the real part of the offset, and \fBb[1]\fR contains the imaginary part of the offset.
.RE

.sp
.ne 2
.mk
.na
\fB\fIn\fR\fR
.ad
.RS 5n
.rt  
Number of elements in the vectors.
.RE

.SH RETURN VALUES
.sp
.LP
Each of the functions returns \fBMLIB_SUCCESS\fR if successful. Otherwise it returns \fBMLIB_FAILURE\fR.
