程序如图利用trapz函数对数组进行积分
但是一直报错:
“错误使用 permute
ORDER 包含无效的 permutation 索引。”
希望好心人指导一下,感谢!

这样就好了
从2开始积分
t=-18.321:0.0022365:18.321;
platform_H=100;
platform_H_error=normrnd(0,1,1,16384)+platform_H;
Dslow_vector=ones(1,16384);
for m=2:16384
t_1=t(1:m);
platform_H_error_1=platform_H_error(1:m);
Dslow_vector(m)=trapz(t_1,platform_H_error_1);
end
