\end{boxedminipage}](img103.png)
Make a matrix of lattice vectors from the lengths a,b,c
and the angles alpha, beta and gamma.
One length must be supplied. Any missing angle is assumed to be 90 degrees
and any missing length is assumed to be a.
The vectors are created in a right-handed order.
- a -- real(dp), intent(in)
-
- b, c -- real(dp), optional, intent(in)
-
- alpha, beta, gamma -- real(dp), optional, intent(in)
-
- Return value --
real(dp), dimension(3,3)
