比如这个函数 function y=f(x) if x<0 y=x.^2+x-6 elseif x>=0&x<5&x~=2&x~=3 y=x.^2-5*x+6 else y=x.^2-x-1; end 我带入x=[-5.0,-3.0,1.0,2.0,2.5,3.0,5.0]进去算出来的不对啊 2matlab中如何对某个函数带入多个数值得出结果?比如这个函数 function y=f(x) if x<...
matlab function if 语句 matlab function if语句 MATLAB是一种强大的数值计算和科学计算软件,它提供了丰富的函数和工具箱,方便用户进行各种复杂的计算和数据分析。在MATLAB中,if语句是一种流程控制语句,用于根据条件的真假来执行相应的代码块。在本文中,我们将一步一步地回答有关MATLAB中if语句的问题,并介绍其...
在matlab中,if 语句可以跟随一个(或多个)可选的 elseif... else 语句,这是非常有用的,用来测试各种条件。\x0d\x0a使用 if... elseif...else 语句,有几点要记住:\x0d\x0a一个 if 可以有零个或else,它必须跟在 elseif 后面(即有 elseif 才会有 else)。 \x0d\x0a一个 ...
x = 42;ifexist('myfunction.m','file') && (myfunction(x) >= pi) disp('Expressions are true')end The first part of the expression evaluates to false. Therefore, MATLAB does not need to evaluate the second part of the expression, which would result in an undefined function error. ...
MATLAB逻辑运算都是针对元素的操作,运算结果是特殊的逻辑数组;在逻辑分析时,逻辑(真)用1表示,逻辑假用0表示,逻辑运算中所有的非零元素作为1处理。go

Simply use "help ischar" and "help isnumeric". Sign in to comment. Walter Roberson on 19 Feb 2012 Vote 0 Link In MATLAB, "if" is not a function: it is a control statement. We've been nagging MathWorks for years to create a function equivalent to "if", but with no success yet...
