Macro: | groupcol | |
Description: | Decomposes a (color) vector into single groups. |
Usage: | {g, gind} = groupcol (col, ncol) | |
Input: | ||
col | scalar or color vector | |
ncol | scalar expected length of colorvector | |
Output: | ||
gcol | m x 1 different colors | |
gind | n x 1 index of groups |
; loads the library graphic library ("graphic") ; generate a color vector, e.g. for swiss banknote col = matrix(100)|(4*matrix(100)) ; computes the different colors {gcol, gind} = groupcol (col, 200) ; show the different colors gcol ; show the index vector (100 ones and 100 twos) gind
decompose a color vector and show the results
