PLOTE

Plot error curves

     H = PLOTE(E,LINEWIDTH,S,FONTSIZE,OPTIONS,'Location',LOCATION,)
     H = E*PLOTE(LINEWIDTH,S,FONTSIZE,OPTIONS,'Location',LOCATION,)

  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
    LOCATION Legend location, default "Best";

Output
H	Array of graphics handles

Description

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, PRROC 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.
