Using and understanding contourc

I would like to compute the contour matrix without plotting. To do this I want to use the contourc command. Unfortunately I don't understand the input of this function.

I have three variables for my data: x,y,z. Each of them is a 20 x 20 matrix and corresponds to the value of my data over a 20 x 20 grid. Using contour I get the wanted result: contour(x,z,y). How do I use contourc in my case? I have read the manual (https://se.mathworks.com/help/matlab/ref/contourc.html?searchHighlight=contourc&s_tid=doc_srchtitle) , but I'm not sure how to construct the input Z.

Hi,

The following links maybe of help to you-

1. contour and contourc
2. contourc- plotting contour matrix

Just adding again that the 'x' and 'y' input to contourc are a single dimensional vectors that specifies the range over which the two dimensions would span.
