MEX-file error-MIDI Toolbox

Hi, I've just added a new path to matlab called Midi toolbox from

https://www.jyu.fi/hum/laitokset/musiikki/en/research/coe/materials/miditoolbox/

Because of using Matlab2013 I have faced with that problem below.

In this link it is also said that in further versions of matlab this problem can be shown and they gave a solution to correct this. But I don't know how to apply this solution. Is there anyone to help me?

Thanks
