SCaVis is a multiplatform environment for scientific computation and data analysis. See http://jwork.org/scavis/. In this tutorial you will learn how to use it. It is useful if have studied Python/Jython before start learning about how to use SCaVis.
Left window is a code editor which can be used to type Python commands. Press the [Run] button on the right to run these commands and to see the output. You can change vertical divider position with the mouse if the output does not fit to the right window.
Let's get familiar with the interactive prompt. Type:
and press [Run]. You will see “ok”. This means that you can talk to the interactive Python.
In some cases you can edit example and run the modified code. In such cases you will see a green border around such codes. Try to change 'ok' to something else and print “output”
If you are not the registered member, you cannot run the code and cannot see the outputs. But you can still read this manual. For example, non-members will see the following code example:without the “Output” button. If you have two commands on the same line, separate them with ”;”.
Here is a small example which shows how to draw a function:
This example can be modified. Replace “x*x” with, say by $cos(x)*x$ and run it again.
You can download the standalone application to work with SCaVis libraries. This application runs on any computer (Windows, Linux, Mac) However, you should be a full member.
