| Macro: | grlinreg2 | |
| Description: | generates a graphical object which contains a linear regression plane from the data. The plane is computed on a rectangular grid with n^2 meshes. |
| Usage: | gl = grlinreg2 (x, {n, {col}}) | |
| Input: | ||
| x | m x 3 matrix | |
| n | 2 x 1 matrix | |
| col | color | |
| Output: | ||
| gl | composed graphical object | |
