Thread Subject: Really interesting!

Hey,

I'm kinda new to matlab. Can anyone help me with this problem:

A function is defined as sqrt(x^2 +(y-3)^2)

I need to write a matlab problem to draw a contour plot of the function in the domain where x varies from 0 to 5 and y from 0 to 5. But a quadrant of radius 2 with centre at the orgin cut through the area. Use a mesh grid of 201x201 and at least 10 contour lines. THe color outside the domain should be white. It seems functions meshgrid,colormap and contourf should be used.

So, what have you done so far for this homework problem? Where did you get stuck?
Also, choose a better subject line in the future

So that you learn something from your homework, simply start by typing the following into the command line

doc meshgrid
doc colormap
doc contour

In the help you will find some help (sounds weird right!)
