Dot product of 2x2 matrix

Web2. The dot notation means to write a sum of three terms by matching x, y, z matrices for the two particles, as if →σ1 were a vector (σ1x, σ1y, σ1z) and likewise for particle #2. →σ1 ⋅ →σ2 = σ1xσ2x + σ1yσ2y + σ1zσ2z. Note that σ1i and σ2i act separately as matrices; they don't multiply with each other. Webdot. alternative matrix product with different broadcasting rules. Notes. The behavior depends on the arguments in the following way. If both arguments are 2-D they are multiplied like conventional matrices. If either argument is N-D, N > 2, it is treated as a stack of matrices residing in the last two indexes and broadcast accordingly. ...
