%First read in data from a file
%   load a:leafstat.dat
%if the file is on a floppy in the a: drive
%Then read in a command file that is
%this file of commands for MATLAB which you have
%saved in a file called lesson1.m on your floppy.
%First tell MATLAB to use the a: drive
%   !a:
%then tell it to run lesson1
%   lesson1
%If the file lesson1.m is not on your floppy but
%rather is on the Math Lab computer, use instead
%   !cd w:\math\math151\mfiles
%and then type lesson1
