/* ============= */
/* > */
/* > \verbatim */
/* > */
/* > ZLATM3 returns the (ISUB,JSUB) entry of a random matrix of */
/* > dimension (M, N) described by the other parameters. (ISUB,JSUB) */
/* > is the final position of the (I,J) entry after pivoting */
/* > according to IPVTNG and IWORK. ZLATM3 is called by the */
/* > ZLATMR routine in order to build random test matrices. No error */
/* > checking on parameters is done, because this routine is called in */
/* > a tight loop by ZLATMR which has already checked the parameters. */
/* > */
/* > Use of ZLATM3 differs from CLATM2 in the order in which the random */
/* > number generator is called to fill in random matrix entries. */
/* > With ZLATM2, the generator is called to fill in the pivoted matrix */
/* > columnwise. With ZLATM3, the generator is called to fill in the */
/* > matrix columnwise, after which it is pivoted. Thus, ZLATM3 can */
/* > be used to construct random matrices which differ only in their */
/* > order of rows and/or columns. ZLATM2 is used to construct band */
/* > matrices while avoiding calling the random number generator for */
/* > entries outside the band (and therefore generating random numbers */
/* > in different orders for different pivot orders). */
/* > */
/* > The matrix whose (ISUB,JSUB) entry is returned is constructed as */
/* > follows (this routine only computes one entry): */
/* > */
/* > If ISUB is outside (1..M) or JSUB is outside (1..N), return zero */
/* > (this is convenient for generating matrices in band format). */
/* > */
/* > Generate a matrix A with random entries of distribution IDIST. */
/* > */
/* > Set the diagonal to D. */
/* > */
/* > Grade the matrix, if desired, from the left (by DL) and/or */
/* > from the right (by DR or DL) as specified by IGRADE. */
/* > */
/* > Permute, if desired, the rows and/or columns as specified by */
/* > IPVTNG and IWORK. */
/* > */
/* > Band the matrix to have lower bandwidth KL and upper */
/* > bandwidth KU. */
/* > */
/* > Set random entries to zero as specified by SPARSE. */
