In this logical operation if all the elements of the array are non-zero then the output will be 1 (true) and If at least one of the elements is zero then the output will be 0 (false).此 MATLAB 函数 返回一个逻辑数组或一个由逻辑值组成的表，其各元素设置为逻辑值 1 (true)；否则，元素是逻辑值 0 (false)。测试将比较数值数组的实部和虚部。当 A 或 B …MATLAB treats any non-zero value as 1 and returns the logical AND. For example (3 & 4) in NumPy is 0 , while in MATLAB both 3 and 4 are considered logical true and (3 & 4) returns 1 . Precedence: NumPy’s & operator is higher precedence than logical operators like < and > ; MATLAB’s is the reverse.Description. example. while expression, statements, end evaluates an expression , and repeats the execution of a group of statements in a loop while the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false.此 MATLAB 函数 对输入 A 和 B 执行逻辑 OR 运算，并返回一个数组或表，其中包含设置为逻辑值 1 (true) 或逻辑值 0 (false) 的元素。如果 A 或 B 在相同的位置包含非零元素，则输出中对应位置的元素将设置为逻辑值 1 (true)。否则，该元素设置为 0。Note that functions are not called in the base workspace. Functions that access the current non-lexical workspace (this is very rare) will therefore not work as expected. For example, matlab.truth = 42, matlab.exist('truth') will not find the truth variable. Use matlab.evalin('base', "exist('truth')", nargout=1) instead in this case.C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™.
