MATLAB: Temperature contour plot from x,y coordinates and corresponding Temperatures

contourplot

Hello everyone,

I have a data set that has the x,y coordinates and their corresponding temperatures (i.e. position based temperatures). How can I draw a plot that will show the temperatures of those positions like contour plot.

Thanks in advance for your time and suggestions. 😀

See if the griddata (link) function will do what you want.

MATLAB: Load x,y

Try this:

x = 1:10;
y1=[0.5 1.7 1.75 1.9 2 2.1 2.4 2.6 2.7 2.9 ]
y2=[0.7 1.8 1.9 2 2.3 2.5 2.7 2.8 2.9 3]
save('XYvectors.mat','x','y1','y2')
D = load ('XYvectors.mat');
x = D.x;
Y1 = D.y1;
y2 = D.y2;

Use whatever file name you want.

See the documentation for the plot function.

MATLAB: Surface fixed point value 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).
