Reading formatted text file in simulink

I have a Simulink model and I need to read a bunch of strings from an ascii text file. I wrote a Matlab script and found using the textscan function works well. However, when I tried creating a MATLAB function block in my model with the code, I get the following error: 'Function 'textscan' is not supported for code generation.

The only direct file input into Simulink I could find is the From File block, however I do not have a .mat file.

Is there a better way to read text files in Simulink? How can I work around the textscan error?

I'm fairly new to Simulink. Running version R2016a.

add to your function

coder.extrinsic('textscan')

Thank you. That does work but eventually I would like to do code generation on this model so I am wary of using this solution.
