Boxes may be represented as expressions or as strings. How can I convert between the two forms? In particular, how can I convert from the string representation to the expression representation? ...

I am trying to avoid dealing with long explicit lists of variables. What i do so far is the following: VarList={x_, y_}; ParList={x, y}; ValList={2, 3}; What ...

Consider I have a list l ...

Generally speaking, With can be used to inject into arbitrarily held expressions, for example: ...

I store a reference to the association in a held expression in a variable: a=<||>; b=Hold[a]; And in the code, I want to do manipulations with the original ...

If you use Plot like this, Plot[Sin[x], {x, 1, 5}] it produces the correct Sin graph ...

I want the function to take in string, then assign a value to its corresponding symbol. An implementation using ToExpression is ...

Seems to me that VerificationTests are a bit verbose: ...

I have been playing with slightly above trivial code manipulations in Mathematica. I thought Mathematica would be great for this kind of work because of rule replacement and expression manipulation, ...
