How to Extract X,Y,Z vectors from grid data?

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?

Well, you forgot to tell us what the data represents...it would appear there's the independent variable information in a record before the actual response data and consequently, that these data sections are repeated for each set of coordinates. One could guess the two integers are size numbers and the two floats are the coordinates...

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)
