surface fixed point value Z

Dear

I want to know the value of Z from the surfc function

That is when I give the value of x, y

It gives me the value of z

surfc (x, y, z)

I do not have the function you used to create the surface in your Question.

Try this with it:

[X,Y] = ndgrid(-2.5:0.1:2.5);                                               % Independent Variable Grid
Z = sin(X).^2 + cos(Y);                                                     % Dependent Variable (Use Your Function)

x_room = 1;                                                                 % X-Room Coordinate
y_room = -1;                                                                % Y-Room Coordinate
z_room = griddata(X,Y,Z, x_room, y_room);                                   % Interpolated Z-Room Coordinate

figure
surfc(X, Y, Z)
hold on
plot3(x_room, y_room, z_room, 'rd', 'MarkerFaceColor','r', 'MarkerSize',10)
hold off
grid on

Substitute your function for mine, and choose whatever you want for the coordinates (providing they are within the specified x and y limits).

Here is it

I mean when I give any point in the room (x,y) already the vlue of z appere
