| Quantlet: | grfdavar | |
| Description: | creates a graphical object from the variance function of a functional object fd |
| Usage: | gdfvar = grfdavar(fd,evalarg,col,art,thick) | |
| Input: | ||
| fd | list, functional (fd) object | |
| evalarg | n x 1, vector, n must equal rows(fd.ccoef) | |
| col | scalar, color, parameter for setmaskl, default is 0 | |
| art | scalar ,art type, parameter for setmaskl, default is 1 | |
| thick | scalar, art type, parameter for setmaskl, default is 2 | |
| Output: | ||
| gdfvar | graphical object containing var function | |
