oldplot — simple plot (old version)
oldplot(x,y,[xcap,ycap,caption]) oldplot(y)
Plot y as function of x. xcap
and ycap are captions for x-axis and y-axis respectively and
caption is the caption of the plot.
Invoked with only one argument, oldplot(y) plots the
y vector or, if y is a matrix, it plots all its
row vectors on the same plot. This plot is done with respect to the vector
1:<number of columns of y>.
oldplot is obsolete. Use plot2d or
plot instead.
