/*  Purpose */
/*  ======= */

/* CSTEGR computes selected eigenvalues and, optionally, eigenvectors */
/* of a real symmetric tridiagonal matrix T.  Eigenvalues and */
/* eigenvectors can be selected by specifying either a range of values */
/* or a range of indices for the desired eigenvalues. The eigenvalues */
/* are computed by the dqds algorithm, while orthogonal eigenvectors are */
/* computed from various ``good'' L D L^T representations (also known as */
/* Relatively Robust Representations). Gram-Schmidt orthogonalization is */
/* avoided as far as possible. More specifically, the various steps of */
/* the algorithm are as follows. For the i-th unreduced block of T, */
/*     (a) Compute T - sigma_i = L_i D_i L_i^T, such that L_i D_i L_i^T */
/*         is a relatively robust representation, */
/*     (b) Compute the eigenvalues, lambda_j, of L_i D_i L_i^T to high */
/*         relative accuracy by the dqds algorithm, */
/*     (c) If there is a cluster of close eigenvalues, "choose" sigma_i */
/*         close to the cluster, and go to step (a), */
/*     (d) Given the approximate eigenvalue lambda_j of L_i D_i L_i^T, */
/*         compute the corresponding eigenvector by forming a */
/*         rank-revealing twisted factorization. */
/*  The desired accuracy of the output can be specified by the input */
/*  parameter ABSTOL. */

/*  For more details, see "A new O(n^2) algorithm for the symmetric */
/*  tridiagonal eigenvalue/eigenvector problem", by Inderjit Dhillon, */
/*  Computer Science Division Technical Report No. UCB/CSD-97-971, */
/*  UC Berkeley, May 1997. */

/*  Note 1 : Currently CSTEGR is only set up to find ALL the n */
/*  eigenvalues and eigenvectors of T in O(n^2) time */
/*  Note 2 : Currently the routine CSTEIN is called when an appropriate */
/*  sigma_i cannot be chosen in step (c) above. CSTEIN invokes modified */
/*  Gram-Schmidt when eigenvalues are close. */
/*  Note 3 : CSTEGR works only on machines which follow ieee-754 */
/*  floating-point standard in their handling of infinities and NaNs. */
/*  Normal execution of CSTEGR may create NaNs and infinities and hence */
/*  may abort due to a floating point exception in environments which */
/*  do not conform to the ieee standard. */

/*          = 'I': the IL-th through IU-th eigenvalues will be found. */
/* ********* Only RANGE = 'A' is currently supported ********************* */

/*  N       (input) INTEGER */
/*          The order of the matrix.  N >= 0. */

/*  D       (input/output) REAL array, dimension (N) */
/*          On entry, the n diagonal elements of the tridiagonal matrix */
/*          T. On exit, D is overwritten. */

/*  ABSTOL  (input) REAL */

/*          and the dot products between different eigenvectors are */
/*          bounded by ABSTOL. If ABSTOL is less than N*EPS*|T|, then */
/*          N*EPS*|T| will be used in its place, where EPS is the */
/*          machine precision and |T| is the 1-norm of the tridiagonal */
/*          matrix. The eigenvalues are computed to an accuracy of */

/*  -- LAPACK auxiliary routine (version 2.0) --   
       Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,   
       Courant Institute, Argonne National Lab, and Rice University   
       September 30, 1994   


    Purpose   
    =======   

    CLARTG generates a plane rotation so that   

       [  CS  SN  ]     [ F ]     [ R ]   
       [  __      ]  .  [   ]  =  [   ]   where CS**2 + |SN|**2 = 1.   
       [ -SN  CS  ]     [ G ]     [ 0 ]   

    This is a faster version of the BLAS1 routine CROTG, except for   
    the following differences:   
       F and G are unchanged on return.   
       If G=0, then CS=1 and SN=0.   
       If F=0 and (G .ne. 0), then CS=0 and SN=1 without doing any   
          floating point operations.   

    Arguments   
    =========   

    F       (input) COMPLEX   
            The first component of vector to be rotated.   

    G       (input) COMPLEX   
            The second component of vector to be rotated.   

    CS      (output) REAL   
            The cosine of the rotation.   

    SN      (output) COMPLEX   
            The sine of the rotation.   

    R       (output) COMPLEX   
            The nonzero component of the rotated vector.

double *r8vec_normal_01_new ( int n, int *seed )

/******************************************************************************/
/*
  Purpose:

    R8VEC_NORMAL_01_NEW returns a unit pseudonormal R8VEC.

  Discussion:

    The standard normal probability distribution function (PDF) has
    mean 0 and standard deviation 1.

  Licensing:

    This code is distributed under the GNU LGPL license.

  Modified:

    06 August 2013

  Author:

    John Burkardt

  Parameters:

    Input, int N, the number of values desired.

    Input/output, int *SEED, a seed for the random number generator.

    Output, double R8VEC_NORMAL_01_NEW[N], a sample of the standard normal PDF.

  Local parameters:

    Local, double R[N+1], is used to store some uniform random values.
    Its dimension is N+1, but really it is only needed to be the
    smallest even number greater than or equal to N.

    Local, int X_LO, X_HI, records the range of entries of
    X that we need to compute.
