Dear experts,
I have two vectors: x and y, and a function u(x,y) representing the temperature in the point (x,y). I want to see different temperatures as different colors, in the XY plane (see an example in the attached picture). i.e.- u will be given as color in the XY plane.
Will someone please help me understand what is the appropriate method to use in order to obtain such a plot?
Thanks in advance

Look at this example
x=1:0.1:4
y=1:0.1:4
[X,Y]=meshgrid(x,y)
Z=sin(X).^2+cos(Y).^2
surf(X,Y,Z)
view(2)

View(2) ignores the last row and col. Any idea how to avoid that? Appending a zero row and col is not working :)

0 <= x <= 1
3 <= y <= 4
z=a(〖xy)〗^0.7 cos(ax)
Create plot. Use function surf
a=input ('a = ');
[x,y]= meshgrid(0:0.1:1,3:3.5:4);
z = a*exp(x*y)^0.7*cos(x*a);
surf(x,y,z);
What is the problem with this model plz
