SIMULINK_MODELING

本子程序包含5个子程序，其主要功能是： （1） 子程序CXCY（E，L，IE，JE）的功能 用于计算各单元的杆件的长度及在结构坐标系中的倾角α的三角函数cosα、sinα。 （2） 子程序ELEA（E，L，IE，JE，A）的功能 用于计算结构坐标系下各单元刚度矩阵中的刚度系数。 （3） 子程序TOTAL（E，LNODE，KE，KZ）的功能 用于形成半带宽的结构原始刚度矩阵。 （4） 子程序FIFX（NP，FXI，FXJ，FYI，FYJ，MMI，MMJ，WL，IE，JE）的功能 它是用来计算各单元的等效节点荷载。 （5） 子程序STIFF（E，KE）的功能 (Book program consists of five sub-programs, and its main functions are: (1) subroutine CXCY (E, L, IE, JE) function The unit used to calculate the length of the bar and in the structure coordinates of the angle α of the trigonometric functions cosα, sinα. (2) subroutine ELEA (E, L, IE, JE, A) function Coordinate system used to calculate the structure of the element stiffness matrix stiffness. (3) subroutine TOTAL (E, LNODE, KE, KZ) function Used to form the structure of semi-bandwidth of the original stiffness matrix. (4) subroutine FIFX (NP, FXI, FXJ, FYI, FYJ, MMI, MMJ, WL, IE, JE) function It is used to calculate the equivalent nodal load of each unit. (5) subroutine STIFF (E, KE) function )

segments image F by using a split-and-merge approach based on quadtree decomposition. MINDIM (a positive integer power of 2) specifies the minimum dimension of the quadtree regions (subimages) allowed. If necessary, the program pads the input image with zeros to the nearest square size that is an integer power of 2. This guarantees that the algorithm used in the quadtree decomposition will be able to split the image down to blocks of size 1-by-1. The result is cropped back to the original size of the input image.
