MATLAB: Do I get the error message “??? Undefined function or variable ‘Nov’.” when trying to retrieve data from yahoo using the FETCH function of Datafeed Toolbox 1.3 (R12.1)

Question

Why do I get the error message "??? Undefined function or variable 'Nov'." when trying to retrieve data from yahoo using the FETCH function of Datafeed Toolbox 1.3 (R12.1)?

This problem only occurs when specifying the 'Period' argument as 'v'. For example:

c = yahoo;
ibm = fetch(c, 'ibm', '01/01/70', '01/01/02','v');

The error message:

 ??? Undefined function or variable 'Nov'.

This code works when other period options are specified, for example 'd', 'm' and 'w'.

Answer 1

This problem has been fixed in Datafeed Toolbox 1.3.1 (R13).

There are no known workarounds for earlier versions of the Datafeed Toolbox.
