Data-coordinate to figure-coordinate conversion.
DC2SC is obsolete, but provided for upward compatibility from
[Xs,Ys] = DC2SC(Xd,Yd) converts vectors or matrices Xd and Yd from
data-coordinates to normalized figure coordinates. In
figure-coordinates, (0.0,0.0) is the lower-left corner of the figure
and (1.0,1.0) is the upper-right corner. For a 2-D plot, (Xmin,Ymin)
is the lower-left corner of the axis box and (Xmax,Ymax) is the upper-
right corner in data coordinates. [Xmin Xmax Ymin Ymax] are the
current axis settings as returned by AXIS .
