This PR for xGELSD has two purposes: 1) fix work space checks in "Path 2a" in CGELSD and ZGELSD 2) add quick return for NRHS=0 to all four xGELSD, since...
**Description** Fix the quick return code for S/D/C/ZGEESX, C/ZHBEVX, S/DSBEVX, C/ZHEEVX, S/DSYEVX, C/ZHPEVX, S/DSPEVX, C/ZHPGVX. 1. set RCONDE and RCONDV in S/D/C/ZGEESX when N = 0. 2. set Q in...
This PR adds a new routine to the BLAS: rotc. The routine accepts an m x (n+1) matrix A and two n x k matrices C and S. The matrices...
Hello, I'm working on a diffusion reaction problem for modelling and I would ideally like to compute diffusion over a 300x300x300 grid. Reading on the subject oriented me towards locally...
In the DSPOVX subroutine the symmetric positive definite matrix A is scaled if (among other criteria) the ratio between the smallest and the largest element of the main diagonal is...
Hello: I can see in older Doxygen documentation (https://netlib.org/lapack/explore-html-3.6.1/files.html) that the LAPACKE folder is present. But in the current https://netlib.org/lapack/explore-html/files.html it is omitted. What is the reason for that? It...
**Description** From the [docs](https://netlib.org/lapack/explore-html-3.6.1/dd/d9a/group__double_g_ecomputational_ga939806608a352efe62d3f5c918ca28c6.html): > DGECON estimates the reciprocal of the condition number of a general > real matrix A, in either the 1-norm or the infinity-norm, using > the...
**Description** Replace unconditional scaling https://github.com/Reference-LAPACK/lapack/blob/2cbabee96f05c52e22167d0005c0b3ba08ef37af/SRC/dstedc.f#L380-L387 with conditional scaling as done in, for example, `steqr`.
**Description** The documentation and the code of GESVJ deviate in two spots with respect to the usage of `.GT.` and `.GE.`: https://github.com/Reference-LAPACK/lapack/blob/4b3d8a46435f57462075f7c8f33b9bd1cf29a1dc/SRC/dgesvj.f#L106 https://github.com/Reference-LAPACK/lapack/blob/4b3d8a46435f57462075f7c8f33b9bd1cf29a1dc/SRC/dgesvj.f#L501 The PR takes the version in the...
Hi, dear developers We found that in blas/lapack, there were some specific subroutines for real symmetric matrix, but none for real skew-symmetric matrix. A survey in lawn 290 had showed...
