[Visual Basic] programming and maths

[Graeme Summers]

Just a little busy right now, but I'm happy to put something together in VB Express.

For Maths teachers, I have a number of applications in the upper senior area: Groups, Leslie Matrices, Markov Chains. I'm always interested in experimenting with Maths applications.

I'm in the research stage of a new edition of 'Programming with Visual Basic' (Express), so challenges like this are good idea starters.

regards,

Graeme Summers

  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?

  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.
