I am trying to plot the value of the function P(x,y) along the line segment that connects (0,0) and (6,4)

P(x,y) = 100*exp(-.4*( (x-1)^2 + 0.7*(y-3)^2))+ 80*exp(-.2*(2*(x-5)^5+1.5*(y-1)^2)); so I am going to use the plot(x.y) function. how do I plot a function along a segment that goes from (0,0) to (6,4) ? I am kind of lost.

You had better pay attention to what Matt has told you. In the second term you will get exp(1251.5) at (0,0) which is an enormous number well above matlab's double precision floating point maximum value. Someone is pulling your leg or you have copied the problem incorrectly.

I think you need to use plot3 for this. You need to first find x and y points you want. For example
x = 0:0.01:6;
y = 4/6*x;
z = x+y;
plot3(x,y,z);
