PLOTE
H = PLOTE(E,LINEWIDTH,S,FONTSIZE,OPTIONS)
| Input | |
| E | Structure containing error curves (see e.g. CLEVAL) |
| LINEWIDTH | Line width, < 5 (default 2) |
| S | Plot strings |
| FONTSIZE | Font size, >= 5 (default 16) |
| OPTIONS | Character strings: 'nolegend' suppresses the legend plot 'errorbar' add errorbars to the plot 'noapperror' suppresses the apparent error plot |
| Output | |
| H | Array of graphics handles |
Various evaluation routines like CLEVAL return an error curves packed in a structure E. PLOTE uses the information stored in E to plot the curves. The remaining parameters may be given in an arbitrary order.
E may contain the following fields (E.ERROR is obligatory)
E.ERROR C x N matrix of error values for C methods at N points (typically errors estimated on an independent test set) E.XVALUES C x N matrix of measurement points; if 1 x N, it is used for all C curves E.TITLE the title of the plot E.XLABEL the label for the x-axis E.YLABEL the label for the y-axis E.NAMES a string array of C names used for creating a LEGEND E.PLOT the plot command in a string: 'plot', 'semilogx', 'semilogy' or 'loglog' E.STD C x N matrix with standard deviations of the mean error values which are plotted if ERRBAR == 1 Note that this is the st. dev. in the estimate of the mean and not the std. dev. of the error itself. E.APPERROR C x N matrix of error values for C methods at N points (typically errors estimated on the training set) E.APPSTD C x N matrix with standard deviations of the mean APPERROR values which are plotted if ERRBAR == 1
These fields are automatically set by a series of commands like CLEVAL, CLEVALF, ROC and REJECT.
The legend generated by PLOTE can be removed by LEGEND OFF. A new legend may be created by the LEGEND command using the handles stored in H.
E may be a cell array of structures. These structures are combined vertically, assuming multiple runs of the same method and horizontally, assuming different methods.
