21 ## @deftypefnx {Function File} {} create_set (@var{x}, "rows") |
| 8887 | 22 ## This function has been deprecated. Use unique instead. |
| 23 ## @end deftypefn | |
| 24 | |
| 3368 | 25 ## Return a row vector containing the unique values in @var{x}, sorted in |
| 26 ## ascending order. For example, | |
| 3426 | 27 ## |
| 3368 | 28 ## @example |
| 29 ## @group | |
| 7344 | 30 ## create_set ([ 1, 2; 3, 4; 4, 2; 1, 2 ]) |
| 3368 | 31 ## @result{} [ 1, 2, 3, 4 ] |
| 32 ## @end group | |
| 33 ## @end example | |
| 7344 | 34 ## |
| 35 ## If the optional second input argument is the string "rows" each row of | |
| 36 ## the matrix @var{x} will be considered an element of set. For example, | |
| 37 ## @example | |
| 38 ## @group | |
| 39 ## create_set ([ 1, 2; 3, 4; 4, 2; 1, 2 ], "rows") | |
| 40 ## @result{} 1 2 | |
| 41 ## 3 4 | |
| 42 ## 4 2 | |
| 43 ## @end group | |
