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...
