PostScript and TrueType letters are created with splines using only a few points for each letter. The MATLAB code below creates a parametric spline with the following data. Note that in the resulting curve, $y$ is not a "function" of $x$ since the curve may take on more than one $y$ value at a given $x$ value; hence a parametric spline is constructed.

MATLAB code:

$($a$)$ Create and print the script letter defined by the following data.

$($b$)$ On the same axes, plot this letter along with the letter doubled in size. $($The command $2**x$ will double the size of the font in the $x$ direction.$)$ Note the ease of scaling the size of a font that is stored in such a way.

$($c$)$ Edit your MATLAB code to use the command comet $(,$ yy$)$ which will animate the drawing of your letter.

$($d$)$ Create and print another script letter.
