What is a Unitary Matrix and How to Prove that a Matrix is Unitary?

In this video I will define a unitary matrix and teach you how to prove that a matrix is unitary. To do this I will demonstrate how to find the conjugate transpose of a matrix and derive an expression using the identity matrix to easily show that a matrix is unitary.

Couldn’t have been better! Well the U matrix had an i-i instead of 1-i but I think everyone knew what was meant. Subscribed!

Prove that a matrix is unitary? More like "Phenomenal educational videos that are a great entry!" Thank you so much for making and sharing these.

This is a great and helpful video but I think there is a little typo at 3:18. There is an 'i' instead of a 1 in the bottom right corner of the bottom right matrix.

i might be misunderstanding the terms but i think its u^.u = I where u^ = read as "u dagger" which is the complex conjugate of U transpose. U^ = U thats a hermitian

Thanks all your explanations are understandable....I subscribed😀

generally i understood it by the example
