Member Function Documentation

◆ demo_fact_hadamard()

static function matfaust::demo::hadamard::demo_fact_hadamard ( )
static

This demo hierarchically factorizes the Hadamard dictionary and then plots the results.

This essentially reproduces figure 2 from [1].

◆ norm_hadamard()

static function matfaust::demo::hadamard::norm_hadamard ( )
static

This demo makes some time comparison between the 2-norm of the Hadamard matrix and its Faust representation for different dimension of the Hadamard matrix.

◆ speed_up_hadamard()

static function matfaust::demo::hadamard::speed_up_hadamard ( )
static

This demo makes some time comparison between (Hadamard matrix)-vector multiplication and (Hadamard factorisation i.e a FAuST)-vector multiplication for different dimension of the Hadamard matrix.
