problem while converting .m file to .vhd using hdl coder matlab 2012a

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;
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

calling the above function through the code below

    load s.mat;
    dwt_aut12(s(1:400,2));
%%%%%%%%%%%%%%

_While converting the coder shows the following error : _ Expecting MATLAB design "dwt_aut12" to be a function and not a script Use help codegen for more information on using this command. even though its a function.

I ran a slightly modified version of your code in R2012b and it does not generate this error. The main change I made was changing the primary input to a single dimension, as a 2-D array is not supported on the input. The original matrix can be reshape() back into the desired format. I also made the testbench file a function as well.

There are further issues to be encountered, but if you make these two changes you should get past this sticking point.

thank u but i'm sending only a single

Convert the file that has the load() and dwt_aut12 call, into a function.
