Question

Find real symmetrical matrix c such that Q=xcx'​

Answer 1

Step-by-step explanation:

A matrix A is symmetric if and only if A =AT. A matrix A is skew-symmetric if and only if A = −AT.

Consider the following matrices:

A=[ 2 6 4 6 −1 0 4 0 −3 ]andB=[ 0 −1 3 6 1 0 2 −5 −3 −2 0 4 −6 5 −4 0 ].
