.SH DESCRIPTION
.sp
.LP
Each of these functions computes the complex vector from two vectors representing the real and imaginary parts.
.sp
.LP
The following equation is used:
.sp
.in +2
.nf
z[2*k]     = r[k]
z[2*k + 1] = i[k]
.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\fIz\fR\fR
.ad
.RS 5n
.rt  
Pointer to the first complex element of the destination vector. \fBz[2*k]\fR contains the real part, and \fBz[2*k + 1]\fR contains the imaginary part.
.RE
