    h(r+1)= (y(x+1)^2)*cos((2*k*pi*t)/l);  Error here

Above, t was defined as

    t = -a/2:a/(2-1);

and a = K*M ==> 4. 64 ==> 256

Hence

    t=[-128:256];

which will have 384+1 = 385 elements. The index r+1 on the LHS is just one element in length.

Dunno what you want or intended, but that's the mismatch.

I have to implement this formula
