The problem was that I knew I had to put the directory containing the LAPACK .lib file in the list of library directories (Tools -> Options -> Projects and Solutions -> VC++ Directories -> Library Files) but forgot that I also had to add it to the "Additional Dependencies" under Project -> (Project Name) Properties -> Linker -> Input.

### numerical analysis - Is lapack getri numerically the same ...

Basically I LAPACK documentation it states for getri. This method inverts U and then computes inv(A) by solving the system inv(A)*L = inv(U) for inv(A). It seems that numerically is a different procedure than solving L*inv(L)=I and then U*inv(A)=inv(L).My understanding is that getri should be faster than getrs.Otherwise it would be no reason of creating this, except maybe of saving some memory ... left_eigenvalues is n-by-n and its columns are the left eigenvalues of matrix, using the definition of left eigenvalue from LAPACK. For real dtypes, eigenvalues and the eigenvector matrices will be complex if and only if matrix has complex eigenvalues. Only available if nmatrix-lapack or nmatrix-atlas is installed.

At the moment we are working on a C++ port of LAPACK. Sound tedious? It is a joy with FLENS!This is because FLENS gives you easy-to-use tools for implementing efficient, robust and reliable numerical software.

### ?getrf| Intel® Math Kernel Library for C

Computes the LU factorization of a general m-by-n matrix. Return Values. This function returns a value info.. If info=0, the execution is successful.. If info = -i, parameter i had an illegal value.. If info = i, u ii is 0. The factorization has been completed, but U is exactly singular. Division by 0 will occur if you use the factor U for solving a system of linear equations. Call any of the clapack_xgetri functions as directly as possible. You probably don't want to call this function. Instead, why don't you try ::clapack_getri, which is more flexible with its arguments?. This function does almost no type checking.

### BLAS | Apple Developer Documentation

The vecLib framework contains nine C header files (not counting vec Lib.h which merely includes the others).. This document describes the functions declared in the header files cblas.h and vblas.h, which contain the interfaces for Apple’s implementation of the Basic Linear Algebra Subprograms (BLAS) API. This document describes a two-level C interface to LAPACK, consisting of a high-level interface and a middle-level interface. The high-level interface handles all workspace memory allocation internally, while the middle-level interface requires the user to provide workspace arrays as in the original FORTRAN interface.

Excel add-in wrappers for LAPACK. This add-in allows you to call LAPACK functions from Excel. It works by creating in-memory C++ objects that return handles that allow Excel to approach the speed of native code.. The functions ARRAY.SET and ARRAY.GET access 2-dimensional arrays of floating point numbers in memory so they don't take up real estate in your worksheet.

### Routines for BLAS, LAPACK, MAGMA - ICL

Routines for BLAS, LAPACK, MAGMA. This re-organizes the LAPACK routines list by task, with a brief note indicating what each routine does. It also includes links to the Fortran 95 generic interfaces for driver subroutines. Not all “BLAS” routines are actually in BLAS; some are LAPACK extensions that functionally fit in the BLAS. .lapack_gesvd(jobu, jobvt, m, n, a, lda, s, u, ldu, vt, ldvt, lwork) ⇒ Object The following are functions that used to be implemented in C, but now require nmatrix-atlas to run properly, so we can just implemented their stubs in Ruby.

## SparseBaseLapack

This method takes one of the ipiv returns from LAPACK and creates the permutation matrix. When factorizing, it is useful to avoid underflows and overflows by reordering rows/and or columns of the input matrix (mostly these methods solve simultaneous equations, so order is not important). CGETRI computes the inverse of a matrix using the LU factorization computed by CGETRF. This method inverts U and then computes inv(A) by solving the system inv(A)*L = inv(U) for inv(A). Does a point wise add of two arrays z = x + y.This can be used to add vectors or matrices. There is no equivalent BLAS routine, but many libraries provide optimized (parallel and/or vectorized) versions of this routine.

A library of general-use Fortran 2003 routines used in many NWTC computer-aided engineering tools (1 reply) The following is a first attempt to almost create a shell script for installation of ATLAS and LAPACK. It does not work right now and it is specific to a particular platform. It is posted here to archive it and throw into the public domain, maybe others will find it useful. It is at least a documentation of some relevant notes on the procedure.
