Undefined function or variable 'iqf'.

This function was introduced in release R2012b. Are you using that release or newer?

If you are, check the output of the ver function. Does it list Datafeed Toolbox, the toolbox that contains the iqf function?

If it does, it's possible that all the licenses for that toolbox are currently in use. Use the license function to check or ask your license adminstrator (probably someone in your IT department.)

>> help iqf

'iqf' requires Datafeed Toolbox.
