error

[heyo]

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).

[anon]

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.
