MATLAB: Surface plot from straight line coordinates and their value on z

3d3d plotsMATLABplot

I'm looking to represent in MATLAB the plot attached.

I have a series of six straight lines coordinates, and every line has a value on z-axis. How can i plot the surface?

Concantenate your data into matrix. Look for surf, see how data should look like

Also you can use griddata

You did not say what you have tried, and what did not work.

Consider:

Z = randn(100);
figure
surf(Z)
view(0,90)

That produces a (100x100) matrix, and the view call lets you look at it from the top, rather than from the side.

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).
