          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 unitary 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 unitary 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\&.
          j=6: The same of 5, but A is scaled down\&.
