       Parameters
           DOTYPE

           !>          DOTYPE is LOGICAL array, dimension (NTYPES)
           !>          The matrix types to be used for testing.  Matrices of type j
           !>          (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) =
           !>          .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.
           !>          The matrix of type j is generated as follows:
           !>          j=1: A = U*D*V where U and V are random orthogonal matrices
           !>               and D has random entries (> 0.1) taken from a uniform
           !>               distribution (0,1). A is full rank.
           !>          j=2: The same of 1, but A is scaled up.
           !>          j=3: The same of 1, but A is scaled down.
           !>          j=4: A = U*D*V where U and V are random orthogonal matrices
           !>               and D has 3*min(M,N)/4 random entries (> 0.1) taken
           !>               from a uniform distribution (0,1) and the remaining
           !>               entries set to 0. A is rank-deficient.
           !>          j=5: The same of 4, but A is scaled up.
