Hi,
I am using Matlab version 2015b.
I can use "cumsum", but not "cusum".
Is it because of different version?
cusum link: cusum matlab link
>> help cusum
cusum not found.
Use the Help browser search field to search the documentation, or
type "help help" for help command options, such as help for methods.
Did you mean:
>> help cumsum

It was introduced into the Signal Processing Toolbox in release R2016a, a later release than what you have.

OK, good. They usually sell you the latest version, which is what you want.

Your present release apparently doesn't have the Signal Processing TB in the license (or not yet installed)...
