Rewrite for loop with find function
显示 更早的评论
The question:
- See the following code. Rewrite the code in one line using the find function.
x=[-1 3 7 2 4 0];
v=[];
for i=1:length(x)
ifx(i)<=2
v=[v, x(i)];
end
end
I have tried x=[-1 3 7 2 4 0]; find(x<=2)
which returns 1 4 6. What I need it to display is -1 2 0
How would I do this? thanks!

The function find returns the indeces according to the condition. So, in order to diplay the values, you might use the following:
x(find(x<=2))
Here is more information.

I fixed the link. It is just the find document. Glad it worked.
If it was helpful, please accept the answer.

"find" is redundant here. You can just use
x(x<=2);
