You can enhance the readability of large numbers by formatting them with commas to separate digits using the "java.text.DecimalFormat" class. See the below code for an example of this:
function numOut = addComma(numIn)
import java.text.*
jf=java.text.DecimalFormat; % comma for thousands, three decimal places
numOut= char(jf.format(numIn)); % omit "char" if you want a string out
end
Then, calling the function will result in a comma separated number.
addComma(10000.12)
% 10,000.12
