def | run_fact (output_dir=DEFT_RESULTS_DIR) |
This demo hierarchically factorizes the Hadamard dictionary and then plots the results. More... | |
def | fig_fact (input_dir=DEFT_RESULTS_DIR, output_dir=DEFT_FIG_DIR) |

def | run_speedup_hadamard (output_dir=DEFT_RESULTS_DIR) |
This demo makes some time comparison between (Hadamard matrix)-vector multiplication and (Hadamard factorisation i.e a FAuST)-vector multiplication for Hadamard matrices of different sizes. More... | |

This essentially reproduces figure 2 from [1].
