The purpose of this script is to evaluate how severe the run-time overhead is when specifying a transform size parameter for FFT and DCT. It has been observed that specifying this parameter increases the run-time, even if the specified size is equal to the size of the input. The objective here is to figure out whether this overhead is a constant…

Created September 22, 2014 07:43
I wrote this Python script as a "bridge" to generate a fake `.aux` file for use with xcite and Biblatex. It is a very crude attempt, but it worked for the case I needed it for. Run it as `python gen_dummy_bib.py document.bbl document_fake.aux`

replace_count = 1
infile = open(str(sys.argv[1]), 'r')
outfile = open(str(sys.argv[2]), 'w')
for line in infile:
if '\\entry' in line:
outfile.write(re.findall('\\\\entry\{[^{]+', line)[0].replace('entry', 'bibcite') + '{' + str(replace_count) + '}\n')
