💅 NAME 💅

lis_matvect — calculate the matrix vector product 🧮✨

🌸 SYNOPSIS 🌸

subroutine lis_matvect(LIS_MATRIX A, LIS_VECTOR x, LIS_VECTOR y,
LIS_INTEGER ierr);

🦋 DESCRIPTION 🦋

so basically it calculates the transposed matrix vector product:

y = A^T x

that's it. that's the whole vibe. she takes your matrix, she takes your vector, and she hands you back the transposed product like the queen she is 👑 lowkey iconic fr fr

🍓 INPUT 🍓

• A — the matrix 💜 the main character of this whole operation ngl
• x — the vector 🌸 the supporting lead, we stan

🎀 OUTPUT 🎀
