| 28 ## contour matrix @var{c} computed by @code{contourc} from the same | |
| 29 ## arguments; see the latter for their interpretation. The contours are | |
| 30 ## ploted at the Z level corresponding to their contour. The set of | |
| 31 ## contour levels, @var{c}, is only returned if requested. For example: | |

| 41 ## | |
| 7317 | 42 ## The style to use for the plot can be defined with a line style @var{style} |
| 43 ## in a similar manner to the line styles used with the @code{plot} command. | |
| 44 ## Any markers defined by @var{style} are ignored. | |
| 45 ## | |
| 7175 | 46 ## The optional input and output argument @var{h} allows an axis handle to |
| 47 ## be passed to @code{contour} and the handles to the contour objects to be | |
| 48 ## returned. | |
