Hello there,
I would like to plot a function of two variables along a line.
For instance, let us consider the function 
in 
. I would like to plot its restriction along the line 
.
in . I would like to plot its restriction along the line .Which is the best way to visualize it?
Thanks a lot.

syms x y(x)
y(x) = x
f = x^2 + y(x)^2
fsurf(x, y(x), f, [0 1])

Thanks a lot for the quick answer. I have another question connected to that. If now I have a collection of points 
in 
such that they represent a line a for such 
I have a value 
representing the value of a function. How could I plot the function in this case?
in such that they represent a line a for such I have a value representing the value of a function. How could I plot the function in this case?%example data
n = 20;
x = sort(rand(1,n));
y = sort(rand(1,n));
z = x.^2 + y.^2 - atan2(y,x);
%do the plotting
plot3(x, y, z)
xlabel('x'); ylabel('y'); zlabel('z')
