How to find the index of the values which are bigger than zero the following case?
There is a vector M contines three value for example, M = [ 0 0.5 0.7] , Note: there is no negative values
How can I write the following progrom:
the first one if the value in index one bigger than zero ... Then I put a condition
the second one if the value in index two bigger than zero ... Then I put a condition
the third one if the value in index three bigger than zero ... Then I put a condition

Simple:
M = [0, 0.5, 0.7];
% the first one if the value in index one bigger than zero ... Then I put a condition
if M(1) > 0
fprintf('Do something because first element is greater than 0.\n')
end
% the second one if the value in index two bigger than zero ... Then I put a condition
if M(2) > 0
fprintf('Do something because second element is greater than 0\n')
end
% the third one if the value in index three bigger than zero ... Then I put a condition
if M(3) > 0
fprintf('Do something because third element is greater than 0\n')
end

Ran in:
M = [ 0 0.5 0.7];
[~,indices] = find(M>0)
indices = 1×2
2 3
