Error using days365

The piece of code below is an example given in the Matlab documentation at https://www.mathworks.com/help/finance/days365.html

NumDays = days365('15-jan-2000', '15-mar-2000')

But running this gives an error message which reads

"Undefined function 'days365' for input arguments of type 'char'".

I am using the matlab online.

I was wondering what was the cause for the error.

i have the same problem, my old code had days365 and now it doesn't do the job

To debug, run the command:

which days365 -all

It should just return one line, like for me:

C:\Program Files\MATLAB\R2017b\toolbox\finance\calendar\days365.m

In case you have something else as first output, you have another function or variable with the same name on the path - a "shadowing" effect.
