1、Character(char) 1)A character is represented in ASCII using a numeric code between 0 to 255(字符通过ASCII用0到255之间的数字代码表示) 2)Create a character or a string by putting them into a pair of apostrophe(将一个字符或字符串放入一对引号中) 示例代码: clc clear s1 = 'h' whos uin...
STR2DOUBLE Convert string to double precision value. X = STR2DOUBLE(S) converts the string S, which should be an ASCII character representation of a real or complex scalar value, to MATLAB's double representation. The string may contain digits, a comma (thousands separator), a decimal point, ...
If str is a 1-by-N or an N-by-1 string array or cell array, then newStr is a string scalar or a cell array that contains one character vector. If str is an M-by-N string array or cell array, then newStr is an M-by-1 string array or cell array. For a string or cell ar...

A string scalar or character vector. A pattern object. The pattern object must refer to only one variable. "A" or 'A'— A variable named A "Var"+digitsPattern(1)— The variable with the name "Var" followed by a single digit Variable index: An index number that refers to the location...
Switch options, specified as a cell array of character vectors, string array, or 1-by-2 categorical array. If you specify an array, it must have two elements. Duplicate elements are allowed. If you specify this property as a categorical array, MATLAB® uses the values in the array, not...
To add text to a single point, specify txt as a character vector or string scalar. For example, text(.5,.5,'my text'). For multiline text: Use a cell array, where each cell contains a line of text. For example, text(.5,.5,{'first','second'}). Use a string array, where ...
