Question

Question 2. Write a MATLAB Function my-fun that takes as its input a vector of numeric values nums and returns a vector whose values are exactly/only the indicies of nums whose values are non- zero. You may not use any built-in MATLAB functions - i.e. find Sample call(s): CALL 1: my-fun( [8 05 0] ) \% would evaluate [1 3] CALL 2: my-fun ( [0 9 0 1 0] ) \% would evaluate [2 4]
Repost pls show clear and correct codes in matlab..

Answer 1

function v = my_fun(vec)
    for i=1:length(vec) % go through all elements of vec
        if vec(i) ~= 0  % if it's not 0
            v(length(v)+1) = i; % then add it's index to v
        end
    end
end

% testing code
my_fun([8 0 5 0])   
my_fun([0 9 0 1 0])
