.SH DESCRIPTION
.sp
.LP
Each of these functions performs an in-place transpose of a square matrix.
.sp
.LP
For real data, the following pseudo code applies:
.sp
.in +2
.nf
for (i = 1; i < mn; i++) {
    for (j = 0; j < i; i++) {
        tmp          = xz[i*mn + j];
        xz[i*mn + j] = xz[j*mn + i];
        xz[j*mn + i] = tmp;
    }
}
.fi
.in -2

.sp
.LP
For complex data, the following pseudo code applies:
.sp
.in +2
.nf
for (i = 1; i < mn; i++) {
    for (j = 0; j < i; i++) {
        tmp0                 = xz[2*(i*mn + j)];
        tmp1                 = xz[2*(i*mn + j) + 1];
        xz[2*(i*mn + j)]     = xz[2*(j*mn + i)];
        xz[2*(i*mn + j) + 1] = xz[2*(j*mn + i) + 1];
        xz[2*(j*mn + i)]     = tmp0;
        xz[2*(j*mn + i) + 1] = tmp1;
    }
}
.fi
.in -2
