Question

A is hermitian matrix show that kA is also hermitian matrix
​

Answer 1

Answer:

A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. ... By turning a small input current into a large output current, the transistor acts like an amplifier. But it also acts like a switch at the same time

Answer 2

Answer:

Hermitian matrices can be understood as the complex extension of real symmetric matrices. typically means the complex conjugate only, and not the conjugate transpose.
