Need Help.

Guys can anyone over help me with this code..
we are doing a small project on speech filter just as a practical...
and we where using this matlab code(.m file) and where getting both non filtered and filtered waveforms, but later on we got to know that we need to perform this on scilab and thus using this function mfile2sci(); we converted our matlab code to scilab(.sci file), but when code to scilab we cant get the output for our filtered wave form. can anyone over have a look at this to codes. i have added both the matlab and scilab code in following order:
1. matlab code

2. scilab code

.m file%filtering of speech signal using FIR-LPF clear all;fp=fopen('C:\Users\Ashish\Desktop\Main\watermark.wav','r');fseek(fp,44,-1);a=fread(fp,1024);plot(a);title('plot of speech signal');xlabel('sample number');ylabel('Amplitude');fs=16000;t=0.00125;Q=fs/2*t;disp(Q);for i=1:10, x(i)=(sin(0.125*pi*i))/(i*pi);enda(11)=0.125;for i=1:10, a(i)=x(Q-(i-1));endfor i=2:11,a(i+Q)=x(i-1);endw1=window(@blackman,21);for i=1:21, z(i)=a(i)*w1(i);endc=conv(a,z);figure;plot(c);axis([1 1024 80 130]);title('plot of filtered speech signal');xlabel('sample number'); ylabel('Amplitude');

Thank you.
