problem while converting .m file to .vhd using hdl coder, matlab 2012a for fixed point conversion

function [XC] = dwt_aut12(x)%#codegen assert(isreal(x)); coder.extrinsic('–sync:on','wavedec'); coder.extrinsic('–sync:on','wrcoef'); coder.extrinsic('–sync:on','conv2'); coder.extrinsic('–sync:on','ddencmp'); coder.extrinsic('–sync:on','wdencmp'); coder.extrinsic('–sync:on','subplot'); coder.extrinsic('–sync:on','plot'); [c,l] = wavedec(x,5,'sym10'); z=wrcoef('a',c,l,'sym10',5); [THR,~,KEEPAPP]=ddencmp('den','wv',z); [XC,~,~,~,PERFL2] = wdencmp('gbl',z,'sym4',4,THR,'h',KEEPAPP);

 subplot(3,1,1);
 plot(z);
 subplot(3,1,2);
 plot(XC);
% subplot(3,1,3)
 %hold on;plot(z(1:400),'b');plot(XC(1:400),'r'); hold off;

while conversion to hdl file error is
: MATLAB command 'wavedec' failed: (MATLAB:UndefinedFunction) Undefined function 'conv2' for input arguments of type though there is no explicit mention of conv2 in my code.
