Dear all, How to save the value of x vector in de vector based on find function?
expected results is : de = [1 4 7 3 10 6 90 1.1 80];
x=[ 1 4 7 3 10 6 0 90 1.1 80]; for i=1:10 de = find(x > 0); end
Many thanks...

Your loop is superfluous, get rid of it. Simpler with logical indexing:
>> x = [1,4,7,3,10,6,0,90,1.1,80];
>> de = x(x>0)
de =
1 4 7 3 10 6 90 1.1 80

"expected results is: [ 0 0 0 4 0 0 7 8 0 10];"
>> x = [1,4,7,3,10,6,0,90,1.1,80];
>> (1:numel(x)) .* (x<=0)
ans =
0 0 0 4 0 0 7 8 0 10
If your professor insists that you use a pointless find, then something like this perhaps:
>> idx = find(x<=0);
>> vec = zeros(size(x));
>> vec(idx) = idx
vec =
0 0 0 4 0 0 7 8 0 10
