- If at home, download
`plotsln.m`from the MATLAB files directory via the web page containing the other M-files and save in the appropriate directory. If at the Emporium,`plotsln.m`is already installed. - Start MATLAB. At home change to the appropriate directory.
At the Emporium copy
`init.m`to the`Student's Folder`. - Change only the following variables in
`init.m``initax=`Enter endpoints that will give some appropriate figure window. You may have to experiment with this, but often the ODE and initial conditions will give you a good indication where to start.`t0=`This is the given initial -value.`x0=`This is the given initial -value.`ftxsln=`RHS of your solution equation .

- Save
`init.m`then type`init`at the command prompt (or copy-and-paste). - Type
`plotsln` - If the plot looks correct, print it.
