It is important to note that laptop.name(1) uses parentheses to representa cell, while laptop.name{1} uses brackets to represent a string. 4、矩阵构造和四则运算(Matrix construction and arithmetic operations) (1)矩阵的定义与构造(Matrix definition and construction) A=[ ] 代表矩阵,B=1:3:15,...
A = ones(1,5); disp(A); In this example, the ones() function creates a row vector with five elements and the resulting vector is displayed: Example 3: Combining ones() with Arithmetic Operations A = ones(2,3)*5; disp(A);
MATLAB represents values that are not real or complex numbers with a special value calledNaN, which stands for “Not a Number”. Expressions like0/0andinf/infresult inNaN, as do any arithmetic operations involving aNaN: x = 0/0 x = NaN ...
MATLAB (matrix algebra)Matlab is a commercial "Matrix Laboratory" package which operates as an interactive programming environment. It is a mainstay of the Mathematics Department software lineup and is also available for PC's and Macintoshes and may be found on the CIRCA VAXes. Matlab is...

In Matlab the arithmetic operations of addition, subtraction, multiplication, and division can be performed in the usual way on scalar quanties, but they can also be used directly with matrices or arrays of data. To use these arithmetic operators on matrices, the matrices must first be created...

2.2.5. Arithmetic operations Arithmetic operations refer to addition, subtraction, multiplication and division of two images or an image and a constant. Images subject to arithmetic operations need to have the same dimensions and grey-scale representation. The resulting image will have the same dimens...
