The code below models a simple SIR model (used in disease control) in Mathematica. (I copied it directly from my notebook).
if say i have a function given : singlepattern = Cosh[theta] + Cosh[3theta] How do i get a rational expression in terms of x of the function if i want to substitute Cosh[theta] by
Condition has attribute HoldAll which prevents evaluation of its first argument before applying the Condition. But for some reason Condition evaluates its first argument even if the test gives False:
I have this specific function to extract parts of a list in the form: Give[list, elem] returns the part of list that corresponds to the position of elem in a global $Reference variable (if defined). I
This is sort of related to my earlier question, but different. I can\'t figure out how to give MathLink function options without using Evaluate(), etc. For example, I have the following C# code:
Examples: In CT = Table[Prepend[10^4*x[range2] /. NDSolve[{...series of equations here...}, {t, range1, range2},
Often I have written: {Min@#, Max@#} & Yet this seem开发者_运维技巧s inefficient, as the expression must be scanned twice, once to find the minimum value, and once to find the maximum value.Is th
In how-do-i-access-the-stackoverflow-api-from-mathematica I outlined how one could use the SO API to get Mathematica to make some interesti开发者_如何学运维ng reputation graphs of top answerers. Could
I just noticed one undocumented feature of internal work of *Set* functions in Mathematica. Consider: In[1]:= a := (Print[\"!\"]; a =.; 5);
