Hi,
I have a plate with mesh of triangular elements. I have specific number for each element. How can I use imagesc to have contourplot of those values? it is different from trisurf function of course?
Thanks

YOu can straight away plot contour with your data. Have a look in the following file exchange function: https://in.mathworks.com/matlabcentral/fileexchange/38858-contour-plot-for-scattered-data
If you want to use imagesc you have to convert your unstructured data into structured data either by using scatteredinterpolant or griddata.

imagesc works on structured grids i.e matrices......tricontour will work....
