Hi @ all,

I was wondering if there is a way to display every character that i type in maple math input without any kind of automatic text editing (neither adding nor removing characters).

I find it very cumbersome to read and edit the modified input (afaik just from looking at a simple piece of printed (black and white on pamper) code it is impossible to destinguish atomic variables and indexed variables due to automatic text edit of the input to lower script in both cases).

Example 1: "True" Low Script (Not indexed variable!)
> a__1 :=3:

When I type this in 2-D Math Input (or Maple Input) the cursor jumps to lower script (atomic variable) after the second underscore which is not what i want to happen. After evaluating the expression it is very neat to see the "1" as lower sript but not during typing. Any mode or something to achieve this?

2. Example: Use a loop for dynamic variable creation (not because it is smart to do so but to illustrate my problem with maple input and automated text edit)

> for i from 1 to 4 do:
> x__||i:=1:
> end do:

I can not type this directly in any kind of maple input I have found. The concatenate symbol will be interpreted as subscript without escaping the automatically entered "atomic variable" mode which causes an error. After I use the arrow key to type "||i" outside "atomic variable mode" the loop variable i is not used as index anymore but instead appended to x as a number. But what i want is a dynamic variable creation with "true" numbered subscripts. I could use a longer version with cat() but this sucks (or I simply do not know how to type it properly).

I do not want to use or see atomic variables during input (or any kind of automatic text editing during input for that matter) !

So what I do Instead is I use a texteditor to type away, paste the code to maple and execute it. Works like a charm and my fingers do not have to leave their designated spots on the keyboard and i can type way faster. Furthermore I can always copy the code back to notepad++ and use regex to make a lot of simultaneous replacements at once whereas this is quite difficult with code that i typed in maple.

So how do I turn off automated text edit of the input? Or should I use anything else then a worksheet?

Hi there,

I was wondering how to define the unit of an unspecified function. Here is what I want to do:

Say I have the coordinates of a Point in 1D-Space denoted by an unknown function x(t). While this function depends on time t the value of this function is supposed to be of SI Unit meter.

When calculating diff(x(t),t) I would like to get something like (absolut derivative of x(t)) * Unit(m/s).

So how do i tell maple that x(t) is something like f: time -> meter?
Also: How to specify that t has unit second without breaking the diff() command?

Any help would be greatly appreciated.

Regards
