I have the below data from contour grid, but I am not sure how to deal with it, the data are more than 3000 rows. I have two questions regarding this data:
1- How can I generate a contour plot from them?
2- How can I extract the X,Y,Z vectors for the data points sets from these data?

If that matrix is the result of a calculation on the ‘X’, ‘Y’, and‘Z’ vectors, it likely cannot be done.
Doing that would be the mathematical equivalent of un-frying an egg.

Is the matrix of data you shared the input to contour(z)?
Is your question how to extract the (x,y,z) coordinates of lines produced by a contour plot with the input matrix you shared?

If you data as given n-by-5, then you can just use surf(z), e.g.:
data = rand(5,50);
surf(data)
