Naming Conventions

Routines🔗

General rules🔗

A BLASFEO routine name is generally build with the following pattern:

blasfeo_{precision}{matrix_type}{operation}{*flags}

The available values are the followings.

Precision🔗

• d: double

• dia: diagonal matrix
• tr: triangular matrix
• row: row
• col: column
• vec: vector

Operation🔗

• mm: matrix-matrix multiplication
• mv: matrix-vector multiplication
• sm: matrix-system solution
• sv: vector-system solution
• cp: copy
• sc: scale
• se: set
• ad: add
• tr: transpose
• in: insert
• ex: extract
• in1: insert one
• ex1: extract one
