In an assignment A(I) = B, the number of elements in B and I must be the same
中文解释：在赋值语句 A(I) = B 中,B 和 I 的元素个数必须相同
出错原因：I 和 B 的维数、大小不一样.这正如“把 5 个水果放到 6 个篮子”、或者“把 6 个水果放到 5 个篮子”,均无法实现
解决办法：自己设置断点调试一下,看看 I 和 B 的维数、大小是否相同,不同的话就要修改成两者一致
举例：
【错误代码】：
代码:
b = [1,2];
s(1) = b;
【正确代码】：
代码:
b = [1,2];
for i = 1:2
s(i) = b(i);
end
当然,这样的赋值使用循环是低效的,因此不提倡
