MATLAB Incorporates LAPACK - MATLAB & Simulink - MathWorks

NettetLINPACK used Level 1 BLAS, which operate on only one or two vectors, or columns of a matrix, at a time. Until now, MATLAB has used carefully coded C and assembly language versions of these Level 1 BLAS. LAPACK's block algorithms also make use of Level 2 and Level 3 BLAS, which operate on larger portions of entire matrices. NettetLinpack Benchmark. The LINPACK Benchmarks are a measure of a system's floating point computing power.
