function plotting in matlab

Hello! :)

I want to plot this function in a graph, but for some reason it doesn't want to that.

this is the function:

a(x-x0)+b*exp(-power((x-xc),2)/lambda)

I already have a group of data, for x and y, and i need to get this function to follow that plot as close as possible.

how do i plot it into ?

Rasmus, check out:

 x      = 0:0.1:10;
 lambda = 2;
 a      = 1;
 b      = 1;
 x0     = 1;
 xc     = 1;
 y      = a*(x-x0)+b*exp(-((x-xc).^2)/lambda);

 plot(x,y)
