I have a m by n data matrix and a m by n index matrix which rearranges the order of the n elements in each row of the data matrix. How can I get an indexed data matrix without using loop? Thanks. 댓글 수: 1 Ahmed A. Selman2013년 3월 30일 ...
Extracting scattered elements from a matrix requires a different style of indexing, and that brings us to our next topic. Linear Indexing What does this expressionA(14)do? When you index into the matrix A using only one subscript, MATLAB treats A as if its elements were strung out in a l...
在使用Matlab时，如果遇到“指标超出矩阵维度”的错误提示，通常是因为你尝试访问矩阵中不存在的元素。比如，假设你有一个3x3的矩阵A，如果你尝试访问A[3,4]，这将会引发错误，因为A的第二维的最大索引是3。因此，建议你在编写代码时，确保索引不超过矩阵的实际维度。为了帮助你更好地理解和避免这种错误...
方阵(square matrix) 一般特指n*n的数组,其它与数组相同 行列式(determinant) 方阵的det值,一般用在解线性方程组中 向量(vector) 特指1*n或n*1的数组,前者称为行向量,后者称为列向量 Matlab中数组元素引用有三种方法: 下标法(subscripts) 索引法(index) 布尔法(Boolean) Matlab的存储顺序是1 4 7 2 5 8...
Index exceeds matrix dimensions.翻译成中文就是 指数超过矩阵维度。意思就是，你矩阵加入定义的矩阵A是 3乘3的矩阵，你在程序里，写了一个 B=A（4,3）；这样的话，Matlab就找不到这第四行第三列的数据，因为你定义的A就三行三列；比如如下代码，你可以试试：M= magic(4);M(6,6)输出的就...
