-* Purpose
-* =======
-*
-* DLASR applies a sequence of plane rotations to a real matrix A,
-* from either the left or the right.
-*
-* When SIDE = 'L', the transformation takes the form
-*
-* A := P*A
-*
-* and when SIDE = 'R', the transformation takes the form
-*
-* A := A*P**T
-*
-* where P is an orthogonal matrix consisting of a sequence of z plane
-* rotations, with z = M when SIDE = 'L' and z = N when SIDE = 'R',
-* and P**T is the transpose of P.
-*
-* When DIRECT = 'F' (Forward sequence), then
-*
-* P = P(z-1) * ... * P(2) * P(1)
-*
-* and when DIRECT = 'B' (Backward sequence), then
-*
-* P = P(1) * P(2) * ... * P(z-1)
-*
-* where P(k) is a plane rotation matrix defined by the 2-by-2 rotation
-*
-* R(k) = ( c(k) s(k) )
-* = ( -s(k) c(k) ).
-*
-* When PIVOT = 'V' (Variable pivot), the rotation is performed
-* for the plane (k,k+1), i.e., P(k) has the form
-*
-* P(k) = ( 1 )
-* ( ... )

-* ( c(k) s(k) )
-* ( -s(k) c(k) )
-* ( 1 )
-* ( ... )
-* ( 1 )
-*
-* where R(k) appears as a rank-2 modification to the identity matrix in
-* rows and columns k and k+1.
-*
-* When PIVOT = 'T' (Top pivot), the rotation is performed for the
-* plane (1,k+1), so P(k) has the form
-*
-* P(k) = ( c(k) s(k) )
-* ( 1 )
-* ( ... )
-* ( 1 )
-* ( -s(k) c(k) )
-* ( 1 )
-* ( ... )
-* ( 1 )
-*
-* where R(k) appears in rows and columns 1 and k+1.
-*
-* Similarly, when PIVOT = 'B' (Bottom pivot), the rotation is
-* performed for the plane (k,z), giving P(k) the form
-*
-* P(k) = ( 1 )
-* ( ... )
