I am trying to call a .dll file in my Matlab code, but getting error:
pawavplayw(y, device, fs, 0, 0, 0, -1);
Undefined function or variable 'pawavplayw'.
The pawavplayw file is a .dll file and is present in the current directory:
The code is working fine, except the above function call. Please help me to solve this.

Mohammad - are you loading this shared library into MATLAB? Is this a C/C++ library? See load C/C++ shared library into MATLAB for details on how to do this.

It looks like those dlls might be old mex files. Mex files used the .dll extension in older 32 bit versions of MATLAB on Windows. If these dll files are mex files then you will need to compile them again from source code to use with a 64 bit version of MATLAB.

Hi Philip Borghesani, long shot but trying my luck here. May I know how can the above mentioned by you be done? I'm dealing with a .dll file which seem like a mex file from almost 2 decades ago.
Thanks.

Hello Alfred Huang. I am getting into the same situation now. Inherited old .dll files written in 2005. Have you found a solution? Thanks!
