I can't figure out how to use ecmnfish

The documentation: http://www.mathworks.com/help/toolbox/finance/ecmnfish.html

The usage: Fisher = ecmnfish(Data, Covariance, InvCovariance, MatrixFormat)

I used Data = randn(50); Covariance = cov(Data)

The error I get:

??? Undefined function or method 'ecmnfish' for input arguments of type 'double'.

Does anyone know the reason for this error?

Thank you for your time, -Andy S.

Hi do you have that product installed? If you enter

>>ver

Do you see the Financial Toolbox in your installation?

[Andrew S]

When I run ver, it says:

Financial Toolbox Version 4.0 (R2011a)

[Wayne King]

Hi Andrew, try

>>license('test','financial_toolbox')

I'm guessing maybe you are in a networked configuration and all the licenses are checked out? or something like that

[Andrew S]

license('test','financial_toolbox') gave "ans=0". I've never used license before so I'm not sure what that implies, though.

[Wayne King]

Hi Andrew, that means that no license is available for that product, are you using MATLAB in a standalone configuration, or in some other configuration.

[Andrew S]

I'm on standalone, I guess I will inquire at my workplace if there are any licensed available.

Thank you for all your help.

[Wayne King]

If that is your own standalone installation, then do contact Mathworks support, they'll sort out the issue for you. If you are worked off a networked configuration, you should have a local MATLAB admin person.

[Andrew S]

I see. The install was delivered to me by my job, but it runs locally on my machine. I guess I will contact our IT department.
