text(X, Y, num2str(number))

for appropriate X and Y coordinates.

However, since the number does not relate to any one object, consider something like

title(sprintf('There were %d objects', number))

Please post the complete text of the error message, and also the current version of your function.

It would also be better if you rewrote to avoid using global variables. See
