and i want a struct array such that: sa(1).a = 1; sa(1).b=s.b=[1 2 3]; sa(2).a=3; sa(2).b=[0 0 0]; and so on. Assignment tosais done in a loop. How do i preallocatesa? I tried sa = struct([]); sa = zeros(1,n);
1. Creation of struct arrays 在Matlab中我们有两种方法来创建结构体数组,一是直接用赋值语句进行创建,二是用函数struct ()函数进行创建。 In Matlab we have two ways to create a structure array, one is directly with the assignment statement to create, the second is to use the function struct () ...

在使用Matlab编写代码时,有时候会遇到 "Index out of bounds because numel(A)=5" 的错误提示。这个错误提示意味着在访问矩阵或向量时,超出了其大小范围。本篇博客将介绍一些常见的解决方案来解决这个问题。 1. 检查索引的范围 首先,需要检查代码中使用的索引是否超出了矩阵或向量的范围。例如,如果一个向量A的长度...
