question: public boolean equals ( Object o ) { if ( ! ( o instanceof Matrix3f ) || o == null ) { return false ; } if ( this == o ) { return true ; } Matrix3f comp = ( Matrix3f ) o ; if ( Float . compare ( m00 , comp . m00 ) != 0 ) { return false ; } if ( Float . compare ( m01 , comp . m01 ) != 0 ) { return false ; } if ( Float . compare ( m02 , comp . m02 ) != 0 ) { return false ; } if ( Float . compare ( m10 , comp . m10 ) != 0 ) { return false ; } if ( Float . compare ( m11 , comp . m11 ) != 0 ) { return false ; } if ( Float . compare ( m12 , comp . m12 ) != 0 ) { return false ; } if ( Float . compare ( m20 , comp . m20 ) != 0 ) { return false ; } if ( Float . compare ( m21 , comp . m21 ) != 0 ) { return false ; } if ( Float . compare ( m22 , comp . m22 ) != 0 ) { return false ; } return true ; }
target:  are these two matrices the same? they are is they both have the same mXX values.
