From the diagram, which shows the linear indices in the upper left corner of each matrix element, you can see thatA(14)is the same asA(2,4). The single subscript can be a vector containing more than one linear index, as in:

In an assignment A(I) = B, the number of elements in B and I must be the same MATLAB:index_assign_element_count_mismatch 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...
