Detailed Description

template<typename CstDerived, typename... Derived>
class tvm::utils::AffineExpr< CstDerived, Derived >

A class representing an affine expression \( A_1 x_1 + A_2 x_2 + \ldots + A_k x_k + b \) where \( A_i \) is a matrix expression, \( x_i \) is a Variable and \( b \) is a vector expression.

The class is essentially a list of LinearExpr in the form of a std:::tuple, and a vector expression.

Template Parameters

CstDerived	The type of the constant part. Possibly NoConstant, otherwise an Eigen expression type with the characteristics of a vector.
Derived	The list of matrix expression types corresponding to each Ai
