Rewrite for loop with find function

The question:

1. 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 tried that and it doesnt work unfortunately and the link to more information is broken

Thanks for leading me in the right direction. I used x=[-1 3 7 2 4 0]; x(find(x<=2)) and it worked

[Erivelton Gualter]

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);
