    I have this defined in my class
    Matrix& operator^(int&); // in class Matrix
    Matrix& Matrix :: operator^(int n)
    Matrix M = *this;
    for(int i=0; i<n-1; i++)
    	M = M * (*this);
    return M;
    and i'm getting this error; error C2511: 'Matrix &Matrix:perator ^(int)' : overloaded member function not found in 'Matrix'

    Look at the argument. In your class declaration you have int&, but in the definition you only have int (no reference).

    You don't probably want to pass the argument by (non-const) reference, because this means you can't use the operator as:

    Matrix m, n;
    n = m ^ 5;
    Also, you are returning a reference to a local, and operator ^ means XOR, not exponentiation.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
