#609 problem with function wavwrite()

[subbireddy pochamreddy]

To convert a.csv file to a.wav file I was tried to use wavwrite() function.but it doesn't work.
every time it says
wavwrite(x1,'L:\TRC01.wav');
In L:/FreeMatPortable/App/FreeMat/toolbox/io/wavwrite.m(wavwrite) at line 64
In docli(builtin) at line 1
In base(base)
In base()
In global()
Error: Illegal request for real part of scalar - this is bug
