[Visual Basic] programming and maths

[Schlanger, Harry P]

Hi Maggie,
 
Here is my suggestion. Should be reasonable to program in MS Access.

*	
	Use a form to enter the initial conditions. In the form, use VBA to do the programming behind a command button.
*	
	Use the database to store the results
*	
	Using the graphing facility to visually display (very basic though)
*	
	Run a query to view the list of iterates

 
It would take quite a bit of time to develop and test.
 
Regards,

Subject: [Visual Basic] programming and maths



One of our maths teachers is looking for a programming solution to the following. Any ideas which language is best for this? Anyone willing to give it a go?

 

Maggie

 

The task is to display successive iterations of z-> z2 +c where z = x+iy and  i is the square root of -1 and c is a complex constant.

 

In particular I want to be able to preset the number of iterations for a given initial value of z (called z(0)) and a fixed (but user selectable) value of c. I'm thinking of a maximum of 1000.

 

I want to see a display of the iterates in a list and a plot on the Argand diagram of each iterate joined to the previous iterate with a line. I want a unit circle fixed on the display . I want to be able to show other circles as user defined. I want to be able to show the Argand diagram with user defined min and max values of Re(z) and Im(z).

 

I would like a reset button to initialise everything. Ideally a zoom in and zoom out feature would be good too.
