Logical operations , More commonly used are &,&&,|,||,~,ischar,isempty,isinf,isnan etc. , The following is an introduction to the use of these common logical operations .

&,&&

expr1 & expr2 Represents logic and operations ;

expr1 && expr2 It is a logic operation with short circuit function , If expr1 Is a logical value 0 (false), Will not be calculated expr2 Result . Each expression must evaluate to a scalar logical value .

|,||

expr1 | expr2 Represents a logical or operation ;

expr1 || expr2 It is a logic operation or with short circuit function , If expr1 Is a logical value 0 (false), Will not be calculated expr2 Result . Each expression must evaluate to a scalar logical value .

~

Non operation , give an example ：

clc;
clear;
close all;
warning off;
