Detailed Description

Efficient matrix transpose. vnl_transpose is an efficient way to write C = vnl_transpose(A) * B. The vnl_transpose class holds a reference to the original matrix and when involved in an operation for which it has been specialized, performs the operation without copying.

If the operation has not been specialized, the vnl_transpose performs a copying conversion to a matrix, printing a message to stdout. At that stage, the user may choose to implement the particular operation or use vnl_transpose::asMatrix() to clear the warning.

NOTE: This is a reference class, so should be shorted-lived than the matrix to which it refers.
