用matlab写出三坐标测量机的21项几何误差程序

三坐标测量机的21项几何误差包括位置误差、姿态误差、直线度误差、平面度误差、圆度误差、角度误差、平行误差等。以下是一个示例程序，可以计算三坐标测量机的位置误差、姿态误差和直线度误差。

% 输入坐标数据
x = [1, 2, 3];
y = [4, 5, 6];
z = [7, 8, 9];

% 计算三坐标测量机的位置误差
mean_x = mean(x);
mean_y = mean(y);
mean_z = mean(z);
range_x = max(x) - min(x);
range_y = max(y) - min(y);
range_z = max(z) - min(z);
position_error = [mean_x, mean_y, mean_z, range_x, range_y, range_z];

% 计算三坐标测量机的姿态误差
x_diff = diff(x);
y_diff = diff(y);
z_diff = diff(z);
roll = atan2(y_diff, z_diff);
pitch = atan2(-x_diff, sqrt(y_diff.^2 + z_diff.^2));
yaw = atan2(sqrt(x_diff.^2 + y_diff.^2), z_diff);
orientation_error = [mean(roll), mean(pitch), mean(yaw)];

% 计算三坐标测量机的直线度误差
linearity_error_x = max(abs(x - mean_x)) - range_x / 2;
linearity_error_y = max(abs(y - mean_y)) - range_y / 2;
linearity_error_z = max(abs(z - mean_z)) - range_z / 2;
linearity_error = [linearity_error_x, linearity_error_y, linearity_error_z];

% 输出结果
disp('Position Error (mean_x, mean_y, mean_z, range_x, range_y, range_z):');
disp(position_error);
disp('Orientation Error (mean_roll, mean_pitch, mean_yaw):');
disp(orientation_error);
disp('Linearity Error (linearity_error_x, linearity_error_y, linearity_error_z):');
disp(linearity_error);

这只是一个示例程序，你需要根据具体的三坐标测量机和测量要求进行修改和完善。
