    Purpose   
    =======   

    CLATM6 generates test matrices for the generalized eigenvalue   
    problem, their corresponding right and left eigenvector matrices,   
    and also reciprocal condition numbers for all eigenvalues and   
    the reciprocal condition numbers of eigenvectors corresponding to   
    the 1th and 5th eigenvalues.   

    Test Matrices   
    =============   

    Two kinds of test matrix pairs   
             (A, B) = inverse(YH) * (Da, Db) * inverse(X)   
    are used in the tests:   

    Type 1:   
       Da = 1+a   0    0    0    0    Db = 1   0   0   0   0   
             0   2+a   0    0    0         0   1   0   0   0   
             0    0   3+a   0    0         0   0   1   0   0   
             0    0    0   4+a   0         0   0   0   1   0   
             0    0    0    0   5+a ,      0   0   0   0   1   
    and Type 2:   
       Da = 1+i   0    0       0       0    Db = 1   0   0   0   0   
             0   1-i   0       0       0         0   1   0   0   0   
             0    0    1       0       0         0   0   1   0   0   
             0    0    0 (1+a)+(1+b)i  0         0   0   0   1   0   
             0    0    0       0 (1+a)-(1+b)i,   0   0   0   0   1 .   

    In both cases the same inverse(YH) and inverse(X) are used to compute   
    (A, B), giving the exact eigenvectors to (A,B) as (YH, X):   

    YH:  =  1    0   -y    y   -y    X =  1   0  -x  -x   x   
            0    1   -y    y   -y         0   1   x  -x  -x   
            0    0    1    0    0         0   0   1   0   0   
            0    0    0    1    0         0   0   0   1   0   
            0    0    0    0    1,        0   0   0   0   1 , where   

    a, b, x and y will have all values independently of each other.
