cfobel/si-prefix | si_prefix/__init__.py | si_format | def si_format(value, precision=1, format_str=u'{value} {prefix}',
exp_format_str=u'{value}e{expof10}'):
'''
Format value to string with SI prefix, using the specified precision.
Parameters
----------
value : int, float
Input value.
precision : int
Number of digits after decimal place to include.
format_str : str or unicode
Format string where ``{prefix}`` and ``{value}`` represent the SI
prefix and the value (scaled according to the prefix), respectively.
The default format matches the `SI prefix style`_ format.
exp_str : str or unicode
Format string where ``{expof10}`` and ``{value}`` represent the
exponent of 10 and the value (scaled according to the exponent of 10),
respectively. This format is used if the absolute exponent of 10 value
is greater than 24.
Returns
-------
unicode
:data:`value` formatted according to the `SI prefix style`_.
Examples
--------

] | Calculate class probabilities for a sequence of data.
Parameters
----------
X : array
Test data, of dimension N times d (rows are time frames, columns
are data dimensions)
A : class transition matrix, where A[i,j] contains p(y_t=j|y_{t-1}=i)
pi : vector of initial class probabilities
inference : can be 'smoothing' or 'filtering'.
Returns:
-------
y_prob : array
An array of dimension N times n_inlier_classes+1, containing
the probabilities of each row of X being one of the inlier
classes, or the outlier class (last column). | [
