| Quantlet: | csort | |
| Description: | csort sorts the rows of a complex matrix with respect to the absolute value of the complex numbers. If a column c is specified the rows of the matrix will be ordered with respect to the elements of column c in ascending (descending) order. |
| Usage: | z = csort(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 complex array | |
