.. todo:: Update the docstring
Execute code in Lpy, and pull some of the results back into the
Python namespace.
In [9]: %lpy -w axiom -n 10 -g
As a cell, this will run a block of Lpy code, without returning any
value::
In [10]: %%lpy
....: p = [-2, -1, 0, 1, 2]
....: polyout(p, 'x')
-2*x^4 - 1*x^3 + 0*x^2 + 1*x^1 + 2
In the notebook, plots are published as the output of the cell, e.g.
%lpy plot([1 2 3], [4 5 6])
will create a line plot.
Objects can be passed back and forth between Lpy and IPython via the
-i and -o flags in line::
In [14]: Z = np.array([1, 4, 5, 10])
In [15]: %lpy -i Z mean(Z)
Out[15]: array([ 5.])
In [16]: %lpy -o W W = Z * mean(Z)
Out[16]: array([ 5., 20., 25., 50.])
In [17]: W
Out[17]: array([ 5., 20., 25., 50.])
The size and format of output plots can be specified::
In [18]: %%lpy -s 600,800 -f svg
