How do I plot MSE of 3D-values?

Hello all,

I've made a Monte Carlo Analysis and with the result of this data I'd like to plot the MSE in a XYZ-mode. The data is a matrix(n by 3) of respective XYZ values.

An example of what I'm trying to achieve is: https://static-content.springer.com/image/art%3A10.1186%2Fs40064-015-1173-6/MediaObjects/40064_2015_1173_Fig13_HTML.gif

Thanks in advance

Those plots would be created by the surfc function, but it wants gridded data and it sounds like you have scatter data.

I wrote a post on the MATLAB Graphics blog recently about how to get from scatter data to gridded data. It should be enough to get you started.

I tried this:

M = [X Y Z];
W = [MSE]
surfc(M(:,1),M(:,2),M(:,3),W);

But then I get the error: The surface Z must contain more than one row or column.

Exactly. You have scatter data and surfc wants gridded data. Follow the link to the blog post about how to grid scatter data.

Thanks, I will keep you updated.

So, I tried to follow the link on your blog post but I'm still in trouble. If I have an XYZ n by 1 matrix and a n by 1 matrix containing the respective MSE's.

How should I proceed?

You basically just need to grid all of your variables using one of the techniques I described there.
