import java.math.*;
>> p=BigInteger('11');
>> m=BigInteger('2');
>> [A,B]=m.gcd(p);
Error using java.math.BigInteger/gcd
Java methods cannot be called with multiple output arguments
How to resolve this issue? I need both A and B.
Thanking in anticipation

@Rik Thank you ver much!
I want to extract the following
[A,B] = gcd(m,p);
if A =1 then
a = mod(B,p)
otherwise a=0
I want to find a which depends on both A and B

@AndresVar, thank you very much but I want to deal with both the outputs.

import java.math.*;
p = BigInteger('11');
m = BigInteger('2');
A = m.gcd(p)
A = 1
B = m.modInverse(p)
B = 6
m.multiply(B).mod(p)
ans = 1

import java.math.*;
p = BigInteger('11');
m = BigInteger('2');
a = inverse(m, p)
a = 6
%cross-check
cross_check = m.multiply(a).mod(p)
cross_check = 1
function a = inverse(b, p)
import java.math.*;
A = b.gcd(p);
if A == BigInteger('1')
a = b.modInverse(p);
else
a = BigInteger('0');
end
end
