For people who isn't familiar with this kind of software any job could appear without any sense; that's why i prepared a project file and a txt with numbers representing the Fibonacci series up to 30.
Fibonacci's is a recursive series working this way:
- F(0)=0, that's the first basic value or step to let the series start;
- F(1)=1, second basic value;
- F(n)=F(n-1)+F(n-2), where n is an integer positive number.
F(4)=F(3)+F(2)=2+1=3; and so on.
With SciDAVis installed, open zip file you downloaded and doubleclick to fibonacci.sciprj which will open a filled table, or open run SciDAVis and by File menu choose "Import ASCII". You're done!
To become a little bit comfortable with it begin playing with some commands and functions; plotting could be very interesting because the graph gives you the behavior, especially when you have a big quantity of numbers which to work with.
For example you can plot loaded series following two steps:
- choose the column to plot. On table's window click on C2[Y] voice on top;
- go to Plot menu -> "Special Line/Symbol" -> Spline.
You'll get same as on right picture.
Adding a third column 3D plotting becomes available.
You can analyze many format pictures (not jpeg) by "Import Image..." voice in File menu: a matrix will be created, not a simple table, with detailed informations about picture.
For example our hw2sw logo returns a matrix (partially visible on left), that 3D-plotted gives the right graph you can rotate and modify even only by colors.
It's possible to export the graph as image directly by right-clicking on it -> Export or from File Menu -> Export Graph.
