💖 lis_matrix_xpay(3f) 💖

okay bestie, welcome to the Lis Library Functions corner of the manual — this one's about smooshing matrices together, and honestly? it's giving main character energy. 🦋

✨ NAME ✨

lis_matrix_xpay — calculate the sum of the matrices

✨ SYNOPSIS ✨

subroutine lis_matrix_xpay(LIS_SCALAR alpha, LIS_MATRIX A, LIS_MATRIX B,
LIS_INTEGER ierr);

✨ DESCRIPTION ✨

So like, what this baby does is calculate the sum of the matrices, and the formula is literally right here, no cap:

B = A + alpha * B

that's it. that's the whole vibe. 🌸

✨ INPUT ✨

  • alpha — the scalar value. yes it's a scalar. it's the little multiplier doing its thing. 💅
  • A, B — the matrices. the actual star material, the two icons in question. 👑

✨ OUTPUT ✨

  • B — becomes A + alpha * B, i.e. matrix B is overwritten. 🫶
heads up bestie: B gets overwritten. like, the original B is gone-gone. she's been replaced by her own glow-up. don't come crying if you needed the old one. 😭

✨ NOTE ✨

Matrices A, B must be in the DNS format. not optional, not negotiable, fr fr. the vibe check is DNS and if you show up in anything else it's not happening. 💀

✨ SEE ALSO ✨

that's the whole page babes, go forth and compute responsibly 🌈⭐
