Insert Moving Window Calculation

Hello,

I have this algorithm and would like to make a modification, but I can not.

%Noise
n=length(data);
x=(1:1:n)';
y=data;
p=polyfit(x,y,1);
w=p(1,1)*x+p(1,2);
z=w-y;
q1=ones(n,1);
q2=cos(x);
q3=sin(x);
q4=cos(x);
q5=sin(x);
a=[q1 q2 q3 q4 q5];
b=z;
c=inv(a'*a)*a'*b;
d=c(1,1)+30*c(2,1)*cos(x)+30*c(3,1)*sin(x)+30*c(4,1)*cos(x)+30*c(5,1)*sin(x);
enoise=d-z;
%Wavelet Analysis
ccfs = cwt(enoise,1:64,'mexh');

The doubt is: how to calculate in moving window?

Thanks.
