lis_matrix_set_type(3f)

💖 NAME 💖

lis_matrix_set_type — bestie, this is the glow-up button for your matrix's storage format ✨

It lives in the Lis Library Functions fam, and it's giving "makeover montage" energy 💅

---

🎀 SYNOPSIS 🎀

subroutine lis_matrix_set_type(LIS_MATRIX A, LIS_INTEGER matrix_type,
LIS_INTEGER ierr);

---

🌸 DESCRIPTION 🌸

Okay so real talk: this routine assigns the storage format. That's it, that's the whole vibe. You hand her a matrix, you tell her what format you want her to be in, and she commits to the bit 🦋

---

✨ INPUT ✨

• A — the matrix 👑 the main character herself, the one getting the makeover
• matrix_type — the storage format 💫 the outfit she's changing into

---

🫶 OUTPUT 🫶

No output bestie, she just does the thing 🙈 (well, except ierr, which is right there in the synopsis doing its little error-code job)

---

💜 NOTE 💜

Not me needing you to know this: when the matrix is created, matrix_type of A is LIS_MATRIX_CSR. Periodt. Default behaviour, no cap 💅

So here's the full menu of storage formats for matrix_type — the whole closet, every fit, laid out for you 🌈

• Compressed Sparse Row (CSR) — {LIS_MATRIX_CSR|1}
• Compressed Sparse Row (CSR) — {LIS_MATRIX_CSR|1}
• Compressed Sparse Column (CSC) — {LIS_MATRIX_CSC|2}
• Modified Compressed Sparse Row (MSR) — {LIS_MATRIX_MSR|3}
• Diagonal (DIA) — {LIS_MATRIX_DIA|4}
• Ellpack-Itpack Generalized Diagonal (ELL) — {LIS_MATRIX_ELL|5}
• Jagged Diagonal (JAD) — {LIS_MATRIX_JAD|6}
• Block Sparse Row (BSR) — {LIS_MATRIX_BSR|7}
• Block Sparse Column (BSC) — {LIS_MATRIX_BSC|8}
• Variable Block Row (VBR) — {LIS_MATRIX_VBR|9}
• Coordinate (COO) — {LIS_MATRIX_COO|10}
• Dense (DNS) — {LIS_MATRIX_DNS|11}

and yes, CSR is listed twice up there — that's exactly how the original rolls, so I'm not touching it. she's an icon, she's a legend, and apparently she's a double feature 👯‍♀️
