4、Relational(Logical)Operators(关系/逻辑运算符) Relational(Logical)Operators(关系/逻辑运算符) 5、几个常用语法 1)if elseif else 例题代码: a = 3; if rem(a,2) == 0 disp('a is even') else disp('a is odd') end 注意: ·"elseif" and "else" are optional(“elseif”和“else”是可...
Logical operators are used in portions of programs known as flow control (for example if . . . else . . . end blocks). Vector or matrix logical operations return vector or matrix output and that flow control blocks require scalar logical expressions. Ope
Certain MATLAB functions and operators return logical values to indicate fulfillment of a condition. You can use those logical values to index into an array or execute conditional code. For more information, see how to Find Array Elements That Meet Conditions.Functions & Find logical AND Short-...
MATLAB offers two types of logical operators and functions −Element-wise − These operators operate on corresponding elements of logical arrays. Short-circuit − These operators operate on scalar and, logical expressions.Element-wise logical operators operate element-by-element on logical arrays. ...
1)Many numerical and logical operators can be applied to strings(许多数字和逻辑运算符可以应用于字符串) 示例代码: str = 'aardvark'; 'a' == str 输出结果:(查找str字符串中,若等于‘a’则为1,否则为0) 2)Try this str = 'aardvark'; 'a' == str str(str == 'a') = 'z' 输出结果:(将...
tf = logical(sym(3)/5 < sym(2)/3) tf = logical 1 To check if several conditions are true at the same time, combine them by using logical operators. For example, check if 1 is less than 2 and if exp(log(x)) == x. Note that when you define a condition that uses other fun...

In this chapter, the reference functions concerned with the logical operators in MATLAB are presented and described. In this regard, several examples and exercises for each section of the chapter are presented. The exercises that include writing the codes, executing them, and achieving the results ...

An expression can include relational operators (such as < or ==) and logical operators (such as &&, ||, or ~). Use the logical operators and and or to create compound expressions. MATLAB® evaluates compound expressions from left to right, adhering to operator precedence rules. ...
