Given a number, format it properly for textual display using the notation $xxx,xxx,xxx.xx. Assume that no more than two digits will follow the decimal point (i.e. you don't have to worry about rounding). Indicate negative numbers with parentheses.
Examples:
Input amt = 34.2 Output str is '$34.20'
Input amt = 91337585 Output str is '$91,337,585.00'
Input amt = -63234922.46 Output str is '($63,234,922.46)'
Input amt = 2784.9 Output str is '$2,784.90'
Note: Answer this problem in Cody and you'll be helping the person on Answers who asked Function to format number as currency?

I believe this is the very first use of the Ans Hack in Cody. See http://blogs.mathworks.com/community/2016/06/23/the-great-ans-hack/

interesting use of strread to turn a string into a cell array (though probably only really useful in cody)
