LinearRegression<double> lr;
Array<double> x,y;
x.push_back(0.0);
x.push_back(1.0);
y.push_back(0.0);
y.push_back(1.0);
lr.setData(x,y);
TEST_EQUALITY_CONST( lr.getSlope(), 1.0 );
TEST_EQUALITY_CONST( lr.getYIntercept(), 0.0 );
}示例2: cos
TEUCHOS_UNIT_TEST( Rythmos_ConvergenceTestHelpers, CoSineData ) {
LinearRegression<double> lr;
Array<double> x,y;
int N = 11;
double dt = 0.1;
for (int i=0 ; i<N ; ++i) {
double xval = dt*i;
x.push_back( xval );
y.push_back( cos(xval) );
}
lr.setData(x,y);
// 1.0e-14 works on rancilio but not on gabriel, exetazo, or s858352
double tol = 1.0e-13;
TEST_FLOATING_EQUALITY( lr.getSlope(), -4.653508042678562e-01, tol ); // These came from matlab
TEST_FLOATING_EQUALITY( lr.getYIntercept(), 1.067025181571952, tol );
