Understanding 2x2 Matrices: Representation and Dot Product
Reply to thread
Message
[QUOTE="Dick, post: 4893646, member: 65100"] I suspect this is a question about Pauli matrices. That notation is shorthand for X=a0*I+sigma1*a1+sigma2*a2+sigma3*a3 where I is the 2x2 identity matrices and sigma1, sigma2 and sigma3 are 2x2 matrices collectively referred to as sigma. The result X is a 2x2 matrix. [/QUOTE]
