MATLAB Code:

% MATLAB fully vectorized code (no loops) to find index number of which the numbers have decreased by 40.

% Initializing vector
z = [ 100 93 90 89 80 79 78 75 67 60 45 42 41 40 30 20 15 12 10 9 2 1];

% Storing index values
indices = 1:length(z);

% Finding index of elements that are decreased by 40
idxLess40 = indices(z < 40);

% Printing to command window
disp(idxLess40);
