ROTMC2QC converts a matrix of complex quaternion matrices to a matrix of complex quaternion vectors Inputs: MC(2m,2n) mxn matrix of real quaternion matrices (each 2x2) Outputs: QC(2m,n) mxn matrix of real quaternion vectors (each 2x1) In matrix form, quaternions can be multiplied and added using normal matrix arithmetic. Each element of an mxn matrix of quaternions is itself a 2x2 block so the total dimension of MC is 2m x 2n.
