变换上三角矩阵MATLAB [英] Transform an upper triangular matrix MATLAB

问题描述

如果我在MATLAB LIKE上有一个上三角矩阵

If I have an upper triangular matrix on MATLAB LIKE

A =

    1 2 3 4
    0 5 6 7
    0 0 8 9
    0 0 0 1

您如何将其转换为:

a =
    1 2 3 4
    2 5 6 7
    3 6 8 9
    4 7 9 1

(转置并保留原始的上三角值)

(transpose and keep the original upper triangular values)

推荐答案

a = A + triu(A, 1)'可以满足您的要求(假设是实数矩阵，或者您想为复杂值使用Hermitian矩阵).

a = A + triu(A, 1)' does what you want (assuming real matrices or you want a Hermitian matrix for complex values).
