→Example Scripts: Add multi-trace example, untested
== Native File Format to MATLAB Workspace ==
The following will convert a single file into a MATLAB workspace:<syntaxhighlight lang="python">
import scipy.io
import numpy as np
def native_to_matlab(prefix):
tracedata = np.load(prefix + '_traces.npy')
textin = np.load(prefix + '_textin.npy')
textout = np.load(prefix + '_textout.npy')
key = np.load(prefix + '_keylist.npy')
scipy.io.savemat('fileout.mat', {
"traces":tracedata,
"textin":textin,
"textout":textout,
"key":key
})
prefix = r'2016.02.24-19.07.03'
#Can point to full directory like:
#prefix = r'C:\Temp\demo\traces_capdir48\knownrand_fixed\knownrand_fixed_P48_data\traces\2016.02.24-19.07.03'
native_to_matlab(prefix)
</syntaxhighlight>This file can be saved in a location where you want the output MATLAB file. You can specify the full directory link if you are not saving the MATLAB file to the same location as the .npy file. This will operate on a single trace-file only, not on an entire set. If you wish to operate on an entire set, you can load all such files and save the output once like this:<syntaxhighlight lang="python">
import scipy.io
import numpy as np
class native_to_matlab(object):
def __init__(self):
self.tracedata = None
self.textin = None
self.textout = None
self.key = None
def add_trace(self, prefix):
_tracedata = np.load(prefix + '_traces.npy')
_textin = np.load(prefix + '_textin.npy')
_textout = np.load(prefix + '_textout.npy')
_key = np.load(prefix + '_keylist.npy')
if self.tracedata is None:
self.tracedata = _tracedata
self.textin = _textin
self.textout = _textout
self.key = _key
else:
self.tracedata.append(_tracedata)
self.textin.append(_textin)
self.textout.append(_textout)
self.key.append(_key)
def write_matlab(self, fname):
scipy.io.savemat(fname, {
"traces":self.tracedata,
"textin":self.textin,
"textout":self.textout,
"key":self.key
})
n2m = native_to_matlab()
prefix_list = [r'2016.02.24-19.07.03'
#Can point to full directory like:
root_dir = r'C:\Temp\demo\traces_capdir48\knownrand_fixed\knownrand_fixed_P48_data\traces\'
for prefix in prefix_list:
n2m.add_trace(root_dir + prefix)
n2m.write_matlab('fileout.mat')
</syntaxhighlight>
