parse error and syntax error while calling from a shell program

[shareefbabu]

Hi
I'm trying to call a octave code(.m) from a shell script. 
When i run that octave code directly from command line the .m code is
working , but when i call from shell code its throwing a parse error:  
syntax error showing my input is wrong. I'm clueless where i'm going wrong.

Anyones help so greatful

Thank you
Shareef

Here are my both shell and .m codes

Shell code calling octave code

speakerinfo=train_fold_1.txt
find ../data_train_test_fold/fold_1 -iname "fold_1_train_1.txt"|

while read line
do
echo $line 
  cat $line | while read uid 
  do
    htinfo=`grep -w ^$uid $speakerinfo |cut -f3 -d" "`
    find ../expt3/globalNORM_200n_mat_1/ -iname "*${uid}*.txt"|
       while read line_in
        do
       spkr_infile=`basename $line_in |cut -f1 -d '.'`
       infile=$line_in
       outfile=../expt3/fold_test_y/${spkr_infile}
echo $htinfo
echo $infile
       octave --quiet --eval "warning off ;
fold_Test_y('$infile''$htinfo');"   # here i'm getting some sparse error, if
i run individually this is running.  
     
     done
   done
 done

octave code :

function [] = fold_Test_y(infile,ht_class)
train_x=load(infile);
class_ht  =ht_class;
[rows_tr col_tr]=size(train_x);
train_y= repmat(class_ht,rows_tr,1);
end
