Mathscript node problem with specgram function

[dan07]

Hello...
I used to use "specgram" function of matlab, in a M file builded to perform FFT spectral analysis in signals. I am trying to build a VI to perform the same action.

In a blank VI I created a Mathscript node and pasted the code of my M file inside it. After adjust the input and output of the node, I run the VI and received the Error message "Unknown symbol on line 7 : specgram"

How do I solve this issue? How do I execute the specgram inside the mathscript node?

Thank you in advance
