From 64fcfd314f594bbc358aa8e2b8dc8def9b288b66 Mon Sep 17 00:00:00 2001 From: Gael Guennebaud Date: Tue, 14 Jun 2016 11:26:57 +0200 Subject: Implement scalar multiples and division by a scalar as a binary-expression with a constant expression. This slightly complexifies the type of the expressions and implies that we now have to distinguish between scalar*expr and expr*scalar to catch scalar-multiple expression (e.g., see BlasUtil.h), but this brings several advantages: - it makes it clear on each side the scalar is applied, - it clearly reflects that we are dealing with a binary-expression, - the complexity of the type is hidden through macros defined at the end of Macros.h, - distinguishing between "scalar op expr" and "expr op scalar" is important to support non commutative fields (like quaternions) - "scalar op expr" is now fully equivalent to "ConstantExpr(scalar) op expr" - scalar_multiple_op, scalar_quotient1_op and scalar_quotient2_op are not used anymore in officially supported modules (still used in Tensor) --- Eigen/src/Core/SelfAdjointView.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Eigen/src/Core/SelfAdjointView.h') diff --git a/Eigen/src/Core/SelfAdjointView.h b/Eigen/src/Core/SelfAdjointView.h index 92c541f08..62d4180da 100644 --- a/Eigen/src/Core/SelfAdjointView.h +++ b/Eigen/src/Core/SelfAdjointView.h @@ -129,7 +129,7 @@ template class SelfAdjointView } friend EIGEN_DEVICE_FUNC - const SelfAdjointView,MatrixType>,UpLo> + const SelfAdjointView operator*(const Scalar& s, const SelfAdjointView& mat) { return (s*mat.nestedExpression()).template selfadjointView(); -- cgit v1.2.3
