还可以用单符号,例如 && 表示两个逻辑值,而 & 表示两个逻辑矩阵,可以用 any, all 等来判断逻辑矩阵的一些情况 if x==5&y==5 且if x==5|y~=8 或可以啊可以的
本次推文将从内容摘要、思维导图、入门学习来介绍Matlab入门学习(1)之if语句、for语句、while语句,其中入门学习分为语句介绍和软件实操。 This tweet will introduce the if statement, for statement, and while statement of Matlab introductory learning (1) from content summary, mind map, and introductory lear...
语法 if expression statements end MATLAB计算表达式,如果产生一个逻辑真或者非零结果,然后就执行一条或者多条MATLAB命令语句。当有嵌套if时,每一个if必须和一个相应的end匹配。当你在if语句里面嵌套使用else if或者else时,一般的格式如下:if expression1 statements1 elseif expression2 statements2 ...
2. To build the model and generate code, press Ctrl+B. The code implementing the if-else construct is in the ex_if_else_SL_step function in ex_if_else_SL.c: /* External inputs (root inport signals with default storage) */ ExternalInputs U; /* External outputs (root outports fed...
if expression, statements, end evaluates an expression, and executes a group of statements when 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. The elseif and else blocks...
