rotmr2qr

PURPOSE ^

ROTMR2QR converts a matrix of real quaternion matrices to quaternion vectors

SYNOPSIS ^

function qr=rotmr2qr(mr)

DESCRIPTION ^

ROTMR2QR converts a matrix of real quaternion matrices to quaternion vectors
 Inputs: 

     MR(4m,4n)   mxn matrix of real quaternion matrices (each 4x4)

 Outputs: 

     QR(4m,n)   mxn matrix of real quaternion vectors (each 4x1)

 In matrix form, quaternions can be multiplied and added using normal matrix 
 arithmetic. Each element of an mxn matrix of quaternions is itself a 4x4 block
 so the total dimension of MR is 4m x 4n.

CROSS-REFERENCE INFORMATION ^
