The error message contains some useful information:

• /home/wided/beamformation_toolbox/bft.mexa64
• This error was detected while a MEX-file was running. If the MEX-file is not an official MathWorks function, please examine its source code for errors. Please consult the External Interfaces Guide for information on debugging MEX-files.
• If this problem is reproducible, please submit a Service Request via: http://www.mathworks.com/support/contact_us/
• A technical support engineer might contact you with further information.

I start with checking bft.c, which seems to contain a bug. If this is not your code, contact the author of the beamformation_toolbox.
