1. 对于下三角矩阵，我们分别检查索引位置`i`和`j`，即行和列。 如果列位置大于行位置，我们只需将该位置设为 0。 2. 对于上三角矩阵，我们分别检查索引位置`i`和`j`，即行和列 ...
Abstract: QR decomposition is a computationally intensive process often required for MIMO detection. A technique that allows a reduction in the computational complexity of MIMO QR detection receivers ...
Let T be an operator-weighted shift whose weights are 2-by-2 matrices. We say that, given ε > 0, T is in the ε-canonical form if each weight is an upper triangular matrix (aij), with 0 ≤ a11, a22 ≤ 1 ...
