- 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/...
