Question 1)

The following is my function z. Please help me to generate a 3D plot and a contour plot.

 function out=z(x,y,n)
 p=(1+sin(5*x))-(1/sqrt(8*(sin(x))))
 q=(1+sin(5*y))+(1/sqrt(8*(sin(y)))) 
if fix(n/2)==n/2
  out=n*(p+q)
 else
  out=(n-1)*(p+q)+p
end

x is in the range of 0 to 6, increment 0.1

y also in the range of 0 to 6, increment 0.1

z is in the range of -0.005 to -2.000

0) 0.1 is called the "increment" there

1) see mesh() and contour()

2) length(m) will be 101, or size(m) will show 1 101

3) Yes.

Change the 1/ to 1./

Enfa White 2012-10-10

I already tried to change / to ./ at the following equations:

p=(1+sin(5*x))-(1./sqrt(8*(sin(x)))); q=(1+sin(5*x))+(1./sqrt(8*(sin(x))));

out=(16*(p+q))./2+p;

When I run it, the empty figure keep opening continuously until I terminate the Matlab program. By the way is there any command that I can enter at the command window to stop this problem? TQ.
