我有一个.mat文件，其中有六列，每个列有一百个数据。我想编写一个函数，该函数将前三列（B，C，D）的每一行与3 x 3矩阵相乘，其中该矩阵是根据sin和cos值计算的，后来包括第四行至第六行（A，E ，F）作为矩阵的最后一列。但是，我没有得到所需的输出。
clear all clc [a] = xlsread('C:Desktop\Book1.xlsx') save data a; matObj = matfile('data.mat'); B = matObj.a(:,1); C = matObj.a(:,2); D = matObj.a(:,3); DX = matObj.a(:,4); DY = matObj.a(:,5); DZ = matObj.a(:,6); rx = [1 0 0; 0 cos(B) -sin(B); 0 sin(B) cos(B)]; ry = [cos(C) 0 sin(C); 0 1 0; -sin(C) 0 cos(C)]; rz = [cos(D) -sin(D) 0; sin(D) cos(D) 0; 0 0 1]; for i = (matObj.a(2,:)):(matObj.a(99,:)) r(i) = (rx*B)+(ry*C)+(rz*D); end %t = [A; E; F]; %T = (r, t)
