First input argument must be a function handle. XMIN must be a floating point scalar. XMAX must be a floating point scalar. YMIN must be a floating point scalar or a function handle. YMAX must be a floating point scalar or a function handle. Unbounded integration region. The integration limits must be finite for the ''tiled'' integration method. Consider using the ''iterated'' method instead. Non-finite result. The integration was unsuccessful. Singularity likely. Reached the minimum rectangle size. The result fails the global error test. Reached the minimum rectangle size. The result passes the global error test. Input function must return ''double'' or ''single'' values. Found ''{0}''. Lower limit size mismatch: size(YMIN(x)) does not match size(x). Upper limit size mismatch: size(YMAX(x)) does not match size(x). Integrand output size does not match the input size. ''AbsTol'' value must be a nonnegative double or single scalar. ''RelTol'' value must be a nonnegative double or single scalar. Reached the maximum number of function evaluations ({0,number,integer}). The result fails the global error test. Reached the maximum number of function evaluations ({0,number,integer}). The result passes the global error test. Method must be ''auto'', ''tiled'', or ''iterated''. Integrand function outputs did not match to the required tolerance when the same input values were supplied in two separate calls with different size input matrices. Check that the function is vectorized properly. The integration was unsuccessful.
