Thanks for the feedback, Nikhil! I did not know that I disabled comment access. I tried to resolve that. Please see if it is accessible now. Also, I can include, improving C parser if that can also be done in the timeline since I am now quite familiar with the C parser code. Currently, while

Dear All, I cannot figure out how to impose a condition. I have a function that is defined as a piecewise function. When it returns its results with several Min(x,y). I would like to substitute Min(x,X) with "x" since

I looked through the proposal and have some suggestions. Can you provide comment access to the people with the link? I think it'd be better to comment directly on the proposal. As for your queries: 1) I will be mentoring for the project. 2) No, you do not need to provide more details in the

assuming() does not work with inequalities yet. The easiest way to simplify the expression at present is to use expr.subs(Min(x, X), x). Aaron Meurer On Mon, Mar 23, 2020 at 9:35 AM Philippe Piot wrote: > > Dear All, > I cannot figure out how to impose a condition. I have a function that is

Hi Philippe, There isn't any way to do this properly right now. We can't use inequalities like `x < X` but we can say that X = x+delta where delta is positive: ``` In [3]: x, X = symbols('x X', real=True) In [4]: e = Min(x, X) In [5]: e Out[5]: Min(X, x) In [6]: delta = Symbol('delta',

Hi, I need a suggestion regarding the timeline. Should I distribute the remaining implementation of C parser(implementing loops and other functions) across all 3 phases or should I complete it in the first phase and then proceed to Java Parser? Suggest any other way if it is better! On Mon 23

The docs are only saying that you don't need the extra rst syntax with :class: or backticks in the See Also section, like you would elsewhere. I suspect the issue in your PR is that the thing you are trying to reference isn't included in Sphinx, so it can't link to anywhere. Aaron Meurer On
