2D Savitzky-Golay Smoothing Differentiation Filter(2-D Savitzky-Golay (SG) Smoothing and Differentiation Filter. The filter coefficients are calculated from the decomposation property of the 2-D SG filters. In addition, the filter coefficients for mixed partial derivative can be obtained by this function. h=sgsdf_2d3(x,y,nx,ny,d,flag_coupling)x = x data point, e.g.,-3:3 (both odd-length)

说明：  一个采用robotstudio做的码垛工作站，里面有ABB机器人运动的所有资料，以及RAPID的详细程序。(A palletizing workstation made of robot studio contains all the information of ABB Robot Movement, as well as the detailed program of rapid.)

说明：  Background Given a set of rectangles {R1, R2, …, Rn}, compute the area of their common intersection. i.e., Area(R1∩R2∩…∩Rn) The edges of the rectangles R1, R2, …, Rn, are either vertical or horizontal lines. For example, the intersection of 4 rectangles, R1, R2, R3, and R4, in the following figure is the shaded rectangle. Input The input contains (N + 1) lines. The first line specifies the number of rectangles N, where 1 < N < 1000. Since the sides of the rectangles are parallel to the x-axis and y-axis, each rectangle is bounded by the lines x = x1, x = x2, y = y1 and y = y2 and each subsequent line of the input file thus specifies one rectangle in the following format: x1 x2 y1 y2 such that 0 <= x1 < x2 <= 10000 and 0 <= y1 < y2 <= 10000, and x1, x2, y1 and y2 are integers. Output The output file contains the area of the intersection of all the rectangles.
