question: protected String instanceToMatlab ( Instance inst ) { StringBuffer result ; int i ; result = new StringBuffer ( ) ; for ( i = 0 ; i < inst . numAttributes ( ) ; i ++ ) { if ( i > 0 ) { result . append ( ( m_UseTabs ? "\t" : " " ) ) ; } result . append ( m_Format . format ( inst . value ( i ) ) ) ; } return result . toString ( ) ; }
