Sort the vector or matrix x.
- Usage
sort(mode, x {, i })- mode
- specifies the sort direction and selects if x is sorted by the values of a row or column
- x
- vector or matrix to be sorted; must be a matrix if mode>1
- i
- row or column containing the sort data; depends on mode (default=0)
- Result
- The sorted vector or matrix x.
