Contour level values must be a vector or a scalar. Contour level values must be finite. Input arguments must be real. Use the function REAL to get the real part of the inputs. Input arguments must have at most 2 dimensions. Contour not rendered for non-finite ZData Contour not rendered for constant ZData X must not be a scalar. X values must be finite. Unknown option "{0}". Number of values in ''XData'' and ''YData'' must equal the number of columns and rows in ''ZData'', respectively. Number of values in ''XData'' must equal the number of columns in ''ZData''. Number of values in ''YData'' must equal the number of rows in ''ZData''. Vector X must be strictly increasing or strictly decreasing with no repeated values. Vector Y must be strictly increasing or strictly decreasing with no repeated values. Number of contour levels must not be negative. First three arguments (X, Y, and Z) must be 2-dimensional, real, non-empty, numeric matrices. First three arguments (X, Y, and Z) must be the same size. Level input must be a numeric scalar. Processing contour failed.
