.SH DESCRIPTION
.sp
.LP
Each of these functions splits a complex vector into separate vectors containing the real and imaginary parts.
.sp
.LP
The following equation is used:
.sp
.in +2
.nf
r[k] = z[2*k]
i[k] = z[2*k + 1]
.fi
.in -2

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

.sp
.ne 2
.mk
.na
\fB\fIi\fR\fR
.ad
.RS 5n
.rt  
Pointer to the first element of the imaginary part.
.RE

.sp
.ne 2
.mk
.na
\fB\fIx\fR\fR
.ad
.RS 5n
.rt  
Pointer to the first complex element of the source vector. \fBx[2*k]\fR contains the real part, and  \fBx[2*k + 1]\fR contains the imaginary part.
.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.
