What is it that defines those pixels? How about if you just picked some column, and erased from there to the center of the image, like
[rows, columns, numberOfColorChannels] = size(binaryImage)
binaryImage(:, 50 : round(columns/2), :) = 0;
I don't know if you just want to pick 50 or some other value, basically manually by turning the axis tick marks on and looking at them, or if you can explain somehow how that column could be automatically chosen.

You went from column 50 to column 28, which means no columns were chosen. You really need to take this 2 hour course to learn how indexing is done:
What you should have done is
[rows, columns, numberOfColorChannels] = size(binaryImage)
% Erase from column 28 to middle of the image.
binaryImage(:, 28 : round(columns/2), :) = 0;
