Femlab

[Tyny]

I want to model in femlab (Matlab add-on) and it produces some strange results. I wanted to find out the cause by plotting some of the expressions to see if one of them was the prob.
How do I plot something entered as an expression?? I could only plot the depended variable, but it produced little information.

Either use a numerical or a symbolic solution.

FOr the numerical method, create a sample grid for your independent variable and create a vector of dependent data based on the equation.

For symbolic you would need the Maple add-on and use the ezplot expression plotter.
