I just downloaded scilab because Wolfram Alpha wouldn't want to plot the function I'd like.

In a physics problem I've found the temperature distribution of a 2 dimensional system. I'd like to visualize this function in 3d.

The function I want to plot is [itex]u(x,y)=\frac{1}{\pi} \arctan \left ( \frac{y+a}{x} \right )+\frac{1}{\pi} \arctan \left ( \frac{a-y}{x} \right )[/itex]. I've read the help file of scilab of how to plot but I'm getting lost very quickly. Any help is appreciated!

Edit: so far I have
. I don't know how to pass a line (enter just evaluates the command I wrote). I get the message "Inconsistent addition."

Code:

`x=[0:0.1:12]'; y=[0:0.1:12]'; z=atan((y-2)/x)+atan((2-y)/2); plot3d(x,y,z)`
