1、Variables do NOT need to be declated before assignment(变量不需要提前申明) 2、A single “equal” sign (=) is the assignment operator(单个等号是赋值操作) 1)Upper case/lower case make difference? ---有 2)Can variable names can begin with a number?---不行 三、Numeric Variable(Data)T...
As an alternative, you can use the plus operator to combine strings. Get str = str1 + ' ' + str2 str = "Good Morning" However, the best practice is to use append when you do not know whether the input arguments are strings, character vectors, or cell arrays of character vectors...

“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: ...

Dimension to operate along, specified as a positive integer scalar. If you do not specify the dimension, then the default is the first array dimension whose size does not equal 1. Consider a two-dimensional p-by-m input array,A:
Compare arrays using isequal rather than the == operator to test for equality, because == results in an error when the arrays are different sizes. Create two arrays. Get A = ones(2,3); B = rand(3,4,5); If size(A) and size(B) are the same, concatenate the arrays; otherwise,...
corresponding elements of two matrices using the .* operator (the matrices must be the same size to do this). E = [1 2;3 4] F = [2 3;4 5] G = E .* F E = 1 2 3 4 F = 2 3 4 5 G = 2 6 12 20 If you have a square matrix, like E, you ca...
