How to find the index of the values which are bigger than zero the following case?

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

M = [ 0 0.5 0.7];
[~,indices] = find(M>0)

indices = 1×2

Then go ahead and write that series of if/else statements. You will have 8 branches.
