legappend appends new entries to the end of a legend by deleting the current legend and recreating a new, similar legend.

legappend('new legend entry')
legappend('new entry 1','new entry 2',...,'new entry N')
[legend_h,object_h,plot_h,text_strings] = legappend(...)

legappend('new legend entry') appends an existing legend with "new legend entry".
legappend('new entry 1','new entry 2',...,'new entry N') adds several new entries to the legend.
legappend('') deletes the last entry from the legend.
legappend('','',...,'') deletes the last several entries from the legend.
[legend_h,object_h,plot_h,text_strings] = legappend(...) returns legend_h, the handle of the new legend; object_h, handles of the line, patch, and text graphics objects used in the legend; plot_h, handles of the lines and other objects used in the plot; and text_strings, a cell array of the text strings used in the legend. Note that for new legend entries, legappend does not add entries to a current legend, but deletes the current legend and recreates a new one. As a result, the legend handle will change with each new-entry use of legappend. The legend handle does not change when legappend is used to delete an entry.
