基于四边形单元有限元原理，计算桁架系统在外力作用下，各节点位移与单元应变。主程序BLOCKMAT.m，从输入文件中读入结点个数，单元个数，结点荷载个数，受约束边界点数，弹性模量，泊松比，厚度，单元定义数组，结点坐标数组，结点力数组，约束信息数组。输入文件inport.txt不同参数代表不同的桁架结构。(Based on quadrilateral finite element principle, calculation of truss system under the action of external force, the displacement of each node and element strain. Main program BLOCKMAT. J m, read from input file node number, cell number, number of nodal load, a constrained boundary points, elastic modulus, poisson s ratio, thickness and unit defined array, node coordinate arrays, nodal force array, array constraints information. Input file inport. TXT different parameters represent different truss structure.)

信号分析里常用，求信号的各种谱,均方谱、功率谱等等！(Commonly used in signal analysis, seeking various spectrum of the signal!)
