I have matrix A that is 100x5 and a matrix B that is 10x2. I want to go through matrix A and delete all rows that have matrix B first column values in matrix A but only from it's first and/or second column (not the other 3). I'm thinking of a foor loop and and if stateme...
The deleted row and column specified in matrix B... I want to delete in A matrix ... 테마복사 B(1)=2 ie 2 row and 2 column delete in matrix A B(2)=3 ie 3 row and 3 column delete in matrix A B(3)=4 ie 4 row and 4 column...
8)num2cell() and mat2cell() 示例代码: a = magic(3) b = num2cell(a) c = mat2cell(a,[1 1 1],3) 代码结果: 注意:M = magic(n)returns ann-by-nmatrix constructed from the integers1throughn2with equal row and column sums. 魔术矩阵:返回由行和列和相等的整数1到n²构成的n乘n矩...
This will produce a single column matrix with all elements of T where corresponding Flag elements are greater than 2. If you want to organize this into different columns then I would suggest keeping the first for loop you have set up.
“Matlab”是“MatrixLaboratory” 的缩写,中文“矩阵实验室”,是强大的数学工具。本文侧重于Matlab的编程语言侧面,讲述Matlab的基本语法,以及用Matlab语言进行程序设计。值得一提的是,Matlab从R2014a版本开始支持中文语言了! 1.基本概念 Matlab默认启动后界面: ...

The shape and contents of the matrix, as well as the elements of the second expression, are immediately visible to the programmer. Spaces in expressions Closely related to this is the usage of spaces in expressions. The rule is, again: put spaces there where MATLAB's syntax would. Consider...
