This tutorial shall help you to use MathPlot the first time.
Introduction
============
You want to try MathPlot. I try to help you:
Let's say, you want to plot the following functions:
sin(x)+cos(x)
2*sin(x)
sin(2*x)
As intervall, you want [-\pi,\pi].
Preparation
===========
Make sure that you have the following files in LIBS:
- mathieeedoubbas.library
- mathieeedoubtrans.library
- asl.library
- mtool.library
- diskfont.library (V36 or higher)
If you work often with MathPlot, copy the following files to S:
- mplot.prefs
- Funktionen.fkt
- Konstanten.con
- Macros.mcr
Start MathPlot with a double-click.
Enter your preferences
======================
If you have not the file "mplot.prefs" in S:, a requesters appears. Just
click on OK.
You should first enter your prefered settings. E.g. use
Preferences/Resolution to set your prefered screenmode. Use "Use" to
see a result. Save your preferences to s:mplot.prefs and restart MathPlot
(or use "Use").
Enter the functions
===================
Well, the three functions are quite short, but to make clear how to use it,
use the macros:
Enter the macros
================
Select the item Macros. A window should appear with two gadgets. Press
the key a. An a$ should appear in the first gadget. Press RETURN.
In the second gadget, enter sin(x) and press RETURN.
Select Macros again. Enter b and cos(x).
Enter the functions
===================
Now you can enter the functions. Select three subitems of the item Change.
A window should appear with a gadget. If there is already some text,
delete it with right-Amiga-x. Then enter _a+_b. Press RETURN. The window
disappears and appears right again. Enter the second function (that is
2*_a). After RETURN, you can enter the last function (that is _a(2*x)).
If you look at the subitem of Change, you should see your functions.
Enter the intervall
===================
Select Intervall. Enter for x-min -pi, for x-max pi, for y-min -20 and for
y-max 20. Both cyclegadgets should be *1.
Plot the functions
==================
Select at Function/... your three functions. They will be plotted. You
will see, that -20/20 was too much.
Change the intervall
====================
You could select Intervall and change it. But you can also use the mouse:
Select Zoom, select one corner of your new intervall, move the mouse and
select the second corner. The screen should be cleared.
Plot axis
=========
Choose Axis/autom.. As colour, choose i.e. 3. Now you are ready.
Discussion
==========
If you want to know more about one of the functions, select Discussion/...
