🌈 Function/Subroutine Documentation 🌈

subroutine SLATTB (integer imat, character uplo, character trans, character
    diag, integer, dimension( 4 ) iseed, integer n, integer kd, real,
    dimension( ldab, * ) ab, integer ldab, real, dimension( * ) b, real,
    dimension( * ) work, integer info)
    SLATTB

💖 Purpose 💖

SLATTB generates a triangular test matrix in 2-dimensional storage. IMAT and UPLO uniquely specify the properties of the test matrix, which is returned in the array A. periodt ✨

🦋 Parameters 🦋

• IMAT — IMAT is INTEGER. An integer key describing which matrix to generate for this path. iykyk 🔑
• UPLO — UPLO is CHARACTER*1. Specifies whether the matrix A will be upper or lower triangular.
  • = 'U': Upper triangular
  • = 'L': Lower triangular
• TRANS — TRANS is CHARACTER*1. Specifies whether the matrix or its transpose will be used.
  • = 'N': No transpose
  • = 'T': Transpose
  • = 'C': Conjugate transpose (= transpose)
• DIAG — DIAG is CHARACTER*1. Specifies whether or not the matrix A is unit triangular.
  • = 'N': Non-unit triangular
  • = 'U': Unit triangular
• ISEED — ISEED is INTEGER array, dimension (4). The seed vector for the random number generator (used in SLATMS). Modified on exit. bestie, it changes on the way out 🫶
• N — N is INTEGER. The order of the matrix to be generated. slay 💅
• KD — KD is INTEGER. The number of superdiagonals or subdiagonals of the banded triangular matrix A. KD >= 0.
• AB — AB is REAL array, dimension (LDAB,N). The upper or lower triangular banded matrix A, stored in the first KD+1 rows of AB. Let j be a column of A, 1<=j<=n.
  • If UPLO = 'U', AB(kd+1+i-j,j) = A(i,j) for max(1,j-kd)<=i<=j.
  • If UPLO = 'L', AB(1+i-j,j) = A(i,j) for j<=i<=min(n,j+kd).
• LDAB — LDAB is INTEGER. The leading dimension of the array AB. LDAB >= KD+1.
• B — B is REAL array, dimension (N).
• WORK — WORK is REAL array, dimension (2*N).
• INFO — INFO is INTEGER.
  • = 0: successful exit
  • < 0: if INFO = -k, the k-th argument had an illegal value

okay that's the whole page, bestie 🎀 — footer sign-off says LAPACK Version 3.12.0, and the page path is /home/abui...IN/slattb.f(3) (no separate date line, just so you know 🫶). mwah 💋
