💖 csr — sparse matrix manipulation 💖

okay bestie, welcome to csr, from the rheolef-7.2 era of your life. this is a manual page, it's giving csr(1rheolef), and it's literally all about making your sparse matrices do a little dance. no cap. 🦋

✨ NAME ✨

csr — sparse matrix manipulation (rheolef-7.2)

🌸 SYNOPSIS 🌸

csr [options] file[[.mtx].gz]

💅 DESCRIPTION 💅

so basically: it plots your sparse matrix, or it manipulates it, or honestly both, main character energy fr fr.

  • it reads from standard input, in the .mtx matrix-market format 🌈
  • it writes to standard output in either matlab or postscript formats

that's the whole vibe. periodt.

🎀 EXAMPLES 🎀

enter your commands like this, bestie:

csr -ps     matrix.mtx | gv -
csr -matlab matrix.mtx > matrix.m

look at her go. 💅✨

👑 OUTPUT FORMAT OPTIONS 👑

pick your fighter:

  • -ps — print in the .ps postscript format. this one is the default, she's the moment, she's always there for you. 💖
  • -mtx — print in the .mtx format. and here's the tea: when the input was not sorted by increasing line and then column order, then, the output is. so it fixes her up for you. iconic behaviour honestly. 🧚
  • -matlab — print in the matlab sparse format (see e.g. octave(1) for more on that). 🍓
  • -name string — specifies a current name for the sparse matlab output option. the default is a. that's it, that's the whole girl. 🫶

😭 LIMITATIONS 😭

no render are yet used for the visualization of the sparse matrix — future developments plane to use gnuplot. so like, she's plotting but she's not plotting-plotting yet. we're waiting on that glow-up. 🙈

⭐ IMPLEMENTATION ⭐

this documentation has been generated from file linalg/bin/csr.cc — yes, she documents herself, we love a self-aware queen. 👑
