Plotting special function (Debye) in Matlab

I'm trying to plot two functions. One is a Debye function in Matlab multiplied by some other stuff and the other is a regular function. How 开发者_StackOverflow社区do I do this? Does Matlab have a toolbox for this?

If you can calculate the function value y(x) at every x you want to plot, you simply write plot(x,y), where each entry in the vector y corresponds to the entry in x for which the function was evaluated. Here's the help for plot.

If you want to plot a function of the form f(x)==0, or f(x,y)=0, you can alternatively use EZPLOT. For example, you can write ezplot('x*sin(x)',-5:0.5:5), which will plot the function x*sin(x) over the interval [-5 5] in steps of 0.5.

I think he means plotting a Debye function.
