Having an issue with the code:
Tried: x ≡ 2 mod 11; 3 mod 12; 4 mod 13; 5 mod 17; 6 mod 19 (result should
be 150999 but get 442719)
Also checked x ≡ 4 mod 11; 3 mod 17 (result should be 37 but get 136)
However, 3 equations work fine!
I have pinned down the problem to M_inv, where it is not looping through
all elements (m) but doing one less (eg 4 instead of 5).
for i=1:length(m)
for j=1:n
if modulo(((M_ratio(i)*j)-1),m(i)) == 0
M_inv(i)=j;
xn(i)=(a(i)*M_ratio(i)*M_inv(i));
end
endend
With the code snippet above, it should iterate 5 times for 5 input
values of a and m, it is not generating M_inv(5), or M_inv(2) (2
equations).
I have verified what the results should be in Maxima CAS,

Any ideas what is going wrong?
Thanks
