Make r a 1x5 vector using rand. Find the elements that have values <0.5 and set those values to 0 (use find).

Confused on how to write this code,

r = rand(1,5); find(r<0.5)=0

tried that, didnt work. anything help. Thanks in advance!

Answer 1

[Walter Roberson]

 idx = find(r<0.5);

Now think about r(idx)

[Muhammad Akhtar]

unsure by what idx means

[Walter Roberson]

find does not return values, find returns locations, also known as indices, which is often abbreviated to idx in English (because the singular of "indices" is "index")
