💖 lis_matrix_set_value — bestie's guide to yeeting a value into a matrix 💖

okay so this is a page from the Lis Library Functions manual (section 3, the library-functions girlies 💅), and it's about lis_matrix_set_value. it's giving "let me put ONE little number exactly where it belongs." no cap.

✨ NAME ✨

lis_matrix_set_value — assign the scalar value to the element of the matrix 🫶

🌸 SYNOPSIS 🌸

#include "lis.h"

LIS_INT lis_matrix_set_value(LIS_INT flag, LIS_INT i, LIS_INT j,
LIS_SCALAR value, LIS_MATRIX A);

like yes she takes five args and she's not sorry about it 💅

🦋 DESCRIPTION 🦋

Assign the scalar value to the (i, j)-th element of matrix A. that's it. that's the whole vibe. one number, one slot, main character energy ✨

👑 INPUT 👑

  • flag — the little mode switch that decides how the value gets dropped in 👇
    • LIS_INS_VALUE — straight up insert mode, babes: A[i, j] = value
    • LIS_ADD_VALUE — add-to-what's-already-there mode: A[i, j] = A[i, j] + value
  • i — The row number of the matrix 📍
  • j — The column number of the matrix 📍
  • value — The scalar value to be assigned 💖
  • A — The matrix 🧚

🌈 OUTPUT 🌈

  • A — The matrix 💜 (she's been updated, she's different now, glow-up complete)

💀 EXIT STATUS 💀

The following exit values are returned:

  • 0 — The process is normally terminated 🎉 everything slayed, no notes
  • unspecified — An error occurred 😭 something went wrong and the vibes are off

🎀 NOTE 🎀

For the multiprocessing environment, the i-th row and the j-th column of the global matrix must be specified. iykyk — don't go handing her local coordinates and then act surprised.

The function lis_matrix_set_value stores the assigned value in a temporary internal format. Therefore, after lis_matrix_set_value is called, the function lis_matrix_assemble must be called. fr fr, do NOT forget this one — you set the value, then you assemble, periodt. 🙈

🔥 SEE ALSO 🔥

that's the whole page bestie, go forth and populate your matrix 💅✨
