.SH DESCRIPTION
.sp
.LP
Each of these functions multiplies a matrix by a scalar and then adds 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, ..., (m*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, ..., (m*n - 1)\fR.
.SH PARAMETERS
.sp
.LP
Each of the functions takes the following arguments:
.sp
.ne 2
.mk

Pointer to the source matrix.
.RE

.sp
.ne 2
.mk
.na

.ad
.RS 5n
.rt  
Pointer to the source offset. When the function is used with complex data types, \fBb[0]\fR contains the offset for the real part, and \fBb[1]\fR contains the offset for the imaginary part.
.RE

.sp
.ne 2
.mk
.na
\fB\fIm\fR\fR
.ad
.RS 5n
.rt  
Number of rows in each matrix.
.RE

.sp
.ne 2
.mk
.na
\fB\fIn\fR\fR
.ad
.RS 5n
.rt  
Number of columns in each matrix.
.RE

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