Scatter plot to contour plot

Can you help me using this function https://www.mathworks.com/matlabcentral/fileexchange/38858-contour-plot-for-scattered-data with the data attached?

I want to go from a scatter plot (below) to a contour plot.

Hi @mads skibsted,

You can use the following code for contour plot of your data:

filePath = 'filePath/k.txt'; % Define the file path
dataMatrix = readmatrix(filePath);
zz = dataMatrix(:, 3);
v=-50:0.001:50; % contour levels
tri=delaunay(dataMatrix(:, 1), dataMatrix(:, 2));
[C,h]=tricontour(tri,dataMatrix(:, 1),dataMatrix(:, 2),zz,v);

Hope this helps!
