[sympy] Re: Substitution of tensor expressions

You can get the tuple of factors of your expression: In [9]: t.args Out[9]: (4, metric(i4, i5), p(L_0), q(-L_0)) Slice away the terms you don't want, and multiply by something else: In [20]: prod(t.args[:2]) * other Out[20]: (4*other)*metric(i4, i5) On Wednesday, 9 March 2016 21:24:38

Jupyter notebooks use MathJax to display LaTeX formulae. MathJax is a Javascript library that renders LaTeX code into HTML. I would be nice to have the MathJax HTML generation in order to add HTML events to the displayed formula. If you succeed to do it, you could also create an IPython widget

Note that you can simply type "%matplotlib notebook" if you want interactive plots from matplotlib in the notebook. Bokeh and mpld3 also give this functionality. Jason moorepants.info +01 530-601-9791 On Wed, Mar 9, 2016 at 8:06 AM, Sartaj Singh wrote: > > I ran the

Thank you, Jason and Aaron for the elaborate reply. I am now a bit clear as to what has to be done if one takes this up. I also understood why you have considered AST as a better option than templating. Also, this is what I construed: 1)An optimization pipeline has to be formulated. I have
