I would like to plot a function but have a domain defined elsewhere as follows: xrange = Sequence[0, 2π]; Plot[Sin[x], {x, xrange}] However, this doesn't work ...

For reusable code it's good practice to use Module[] to localize iteration variables used by Table[], as explained by this post. ...

I need to generate regularly spaced samples (points) from the surface of unit simplexes with 2 or greater vertices or end points. I can generate random samples pretty straightforwardly: ...

I want to return a Hold expression but with some parts pre-evaluated. The easiest way to explain this is probably through code example. Here is what I have ...

question is as follows define a list ttt={1,2}; and if I set values in this way {ttt[[1]],ttt[[2]]}={3,4} then the value ...

Let's say I want to take this plot: r = 3; DensityPlot[x^2 + y^2, {x, -r, r}, {y, -r, r}] and make the x and y limits be returned from some function (maybe because ...

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

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 would like to override the behavior of Dot, so that Dot[u,v] will return a scalar instead of a 1x1 matrix in the case that the ...

I would like to get a list of variable names as strings. For example, x = 1; y = 2; Map[SymbolName, Unevaluated /@ Unevaluated@{x, y}] {"x", "y"} This works ...
