I am trying to write a code that finds maximum value and its range. However, I want the code to find the next maximum value but the previous maximum value is removed or set to zero. This is what I got so far.

 x = Data(:, 1); % import Y of column 1 from Data
 B = zeros(1,100000000); % pre-allocate B
 for n = 1:500
    [M,I] = max (x);
    B(n) = M;
    x(I) = -Inf;   
    if M > 2 % set threshold
        c = x(I-299 : I+700); % range of data points to be taken from x
        c = c'; % transpose c
        pulse(n,:) = c; % n-th row of pulse
    end
 end

The code does not remove the maximum value and its range. I have tried putting c = 0 and x(I-299:I+700) = 0 but they don't work. And I am still unsure where do I have to insert it.
