kron#

Perform a Kronecker product of two operators

template<typename T1, typename T2>
auto __MATX_INLINE__ matx::kron(T1 a, T2 b)#

Kronecker tensor product

The Kronecker tensor product is formed by the matrix b by ever element in the matrix a. The resulting matrix has the number of rows and columns equal to the product of the rows and columns of matrices a and b, respectively.

Template Parameters:

  • T1 – Type of first input

  • T2 – Type of second input

Parameters:

  • a – Operator or view for first input

  • b – Operator or view for second input

Returns:

New operator of the kronecker product

Examples#

auto bv = make_tensor<dtype>({2, 2});
auto ov = make_tensor<dtype>({8, 8});
bv.SetVals({{1, -1}, {-1, 1}});

(ov = kron(eye({4, 4}), bv)).run(exec);
