I´ve got a problem concerning inserting a Tikz-Plot from Matab into my Tex-file. The matlab-script I use to produce the plot is (Contourf-Plot):

The resulting plot, I get in Matlab is:
When I use \input in latex to insert the tikzpicture, my latex-result is:
there is no problem at all, when I use contour instead of contourf in matlab or surf instead of contourf. But anyway, what I need is a filled contour plot with isoloines. Can anybody help me?
This is my Input for the matlab-Skript:

As mentioned in the comments, the underlying problem is a bug in
matlab2tikz.However,
pgfplots1.14 (release date august 2016) supports filled contour plots out of the box and without 3rd party tools. Your example needs can be visualized as follows:.mfile as-is, and run.
P.datinpgfplotsas follows:.
The instruction
mesh/cols=20,mesh/ordering=y variestellspgfplotshow to import the data file wherepatch type=bilinearimproves the quality of the result.Here,
colorbar as legendconfigures the colorbar to describe all employed labels. Note thatcontour filledinpgfplotscomes without label nodes inside of the image.
