Numerical Integration

Generally speaking when you are numerically evaluating and integral, say in MATLAB do I just pick a large number for the bounds or is there a way to tell MATLAB to \"take the limit?\"[详细]

Numerical integration of a function with values known at a given point set (finite and discrete) over an area bounded by discrete points?

Let D be the area bounded by a series of points {x_i,y_i} (1<=i<=N).(The area need not to be convex and the points are supposed to go along the boundary curve.)[详细]
