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.
