What is wrong with following code?
显示 更早的评论
function Z =ush25(x)
x(1)=x;
x(2)=y;
z=3*sin(0.5+0.25.*x(1).*x(2).*cos(x(1)))
end
I get Error in ush25 (line 3) x(1)=x;
What can I do?

@Altin Guberi: please edit your question and show the complete error message. This means all of the red text.

x(1) = x;
There are two possibilities:
- x is scalar, i.e. it has only one element. In which case, the above is simply assigning x to itself. The line is completely pointless
- x is not scalar. In which case it tries to assign the whole of x to the first element of x. This is not going to work. You can't put multiple elements into one element. This is probably why you get an error.
Either way, the line makes no sense. Without knowning what it is you're trying to do, that's all we can say.

We can say one more thing: the next line you are trying to assign y to the second element of x. y does not exist at that point, so that line will result in an error as well.

y could theoretically be a function name, so the line is not definitely wrong.... just very very likely so.
