| Quantlet: | csortcol | |
| Description: | sorts with respect to either a real part of a column or an imaginary part of a column c. If 1 <= c <= cols(xr) it sorts after the real part of x, if cols(xr) < c <= cols(xr)+cols(xi) it sorts the imaginary part after column c-cols(xr). |
| Usage: | z = csortcol(x, c) | |
| Input: | ||
| x | n x p x d1 x ... x dn complex array | |
| c | scalar column of x | |
| Output: | ||
| z | n x p x d1 x ... x dn array real part of sorted x | |
