|
| |
Can someone recall where I saw an article by Wolfram on how to lay out pages, graphics etc. I recall seeing a diagram with print registration marks and some idea of how to use printer points etc. I thought it was one of the tutorials but cant find it .....

With[..] not working with $Output
|
| |
Hello, does anybody have an idea why redirecting output using a With does not work (version 7 Vista)? Consider redefining the list $Output: fun1 := ( old = $Output; $Output = {OpenWrite["c:/tmp.txt"]}; Print["gaga"]; Close["c:/tmp.txt"]; $Output = old;) fun1; fun2 := With[{$Output = {OpenWrite["c:/tmp.txt"]}},... more »

Lists of Equations
|
| |
Hello, I have just started using Mathematica, and I wonder what the easiest way to manage a large set of equations is. I have a bunch of differential equations y1'[x] = z1[x] y2'[x] = z2[x] ... yn'[x] = zn[x] and I have grouped them together in a list like eqs = {y1'[x]==z1[x], ..., yn'[x]==zn[x]} which fits perfectly as an argument to NDSolve. However, I think that,... more »

Solve Minus Sign
|
| |
Dear Group- How can one get rid of the minus sign in: In: Factor[Solve[Rr/s == Rr + x, x]] Out: {{x -> -((Rr (-1 + s))/s)}} We'd like Mathematica to provide answers with the minus sign "multiplied through" (remove Factor[] doesn't solve the problem) Thank you in advance all.
