MATLAB CONTOURC returns a contour matrix that summarizes the contour lines. Although compact, it takes an extra step to decipher the matrix. CONTOURCS wraps CONTOURC function to return the content of the contour matrix as an easily accessible structure array.

S = CONTOURCS(Z) returns a struct array with fields:

S(n).Level - level of the n-th contour line
S(n).Length - number of points for the n-th contour line
S(n).X - X coordinate vector (S(n).Length samples)
S(n).Y - Y coordinate vector (S(n).Length samples)

CONTOURCS supports all the CONTOURC input argument forms.

Very useful, well-written and tidy code, clearly documented, and still very relevant. This is how the CONTOUR family should have returned the contour vertex data.

My only minor request would be to allow the input to be the M matrix itself, rather than assuming that the user wants to call CONTOURC.
