- dddd1111 (input/output)
- On input, this value is the first diagonal element of the scaling
- matrix DDDD. On first call to DROTMG or SROTMG, this value is
- typically 1.0. Subsequent calls typically use the value from the
- previous call.
- On output, this value is the first diagonal element of the
- updated scaling matrix DDDD''''.
-
- dddd2222 (input/output)
- On input, this value is the second diagonal element of the
- scaling matrix DDDD. On first call to DROTMG or SROTMG, this value
- is typically 1.0. Subsequent calls typically use the value from
- the previous call.
- On output, this value is the first diagonal element of the
- updated scaling matrix DDDD''''.
-
- xxxx1111 (input/output)
- On input, this value is the _x-coordinate of the vector used to
- define the angle of rotation before scaling (multiplying by the
- matrix D).
- On output, this value is the _x-coordinate of the rotated vector
- before scaling (multiplying by the matrix D').
-
- yyyy1111 (input/output)
- On input, this value is the _y-coordinate of the vector used to
- define the angle of rotation before scaling (multiplying by the
- matrix D).
- On output, this value is the _y coordinate of the rotated vecttor
- before scaling (multiplying by the matrix D').
