## Converting fractures to regular numbers...

Question is easy but not for me :). How do I convert fractures into regular numbers. Thank you! Greetz Pieter

## Convert Maple formulas to Matlab code...

Hello, I would like to convert Maple solutions to Matlab code. Is there a simple package or Maple code doing that ? I do not want to create a permanent link between Maple and Matlab with a toolbox but simply convert the Maple code to a Matlab code. Thanks a lot ! Guillaume

## how to convert equation in the maple?...

I am a starter of the maple, now i have a problem of the equation of convert. the equation is like that: D(x1):=a1*fx+a2*gx-alpha*Ab; need a commend to convert equation gx:=...... but i don't know which commend can i apply in the Maple?

## Can't open .ms old Maple worksheets...

Hello, Does anyone know how I can open/convert some (old?) Maple worksheets which have the extension .ms? I'm using Maple 10 now, and I just found these old files that I need to use. Thank you all in advance for any ideas or suggestions. FB

## Origami 2D fold

by:
I try to solve a large class of origami folds using Maple, this is the mw file (at this stage, only one step missing, I'm not very good with trigonometry using Maple).

At this end I only have to express the angle alpha in function if the anlgle theta and the lengths y_a and y_b.

More explainations soon.

## Q: using sscanf...

I do not understand how to use this command (on strings), I want to convert
outputs from PARI like below - any hints for me doing that?

"5.2185454343674342011212095337 E444" ->
5.2185454343674342011212095337E444
"0.E-66*I" ->
0.I

"0.14237172979226366716527232070 +
3.1415926535897932384626433833*I"
which would work with 'parse', but not if exponential notation is involved.

## How do I convert rational powers to floating point...

Hi folks, I'm using the IntegralTools(Change) function to change the variables of integration in a double integral to lower the order of a polynomial under a radical prior to integration (praise to Axel!). The result contains exponents under the radical and in the limits of integration that seem to defy Maple's numerical integration routines. (Sorry for not using HTML! I tried to present in 2D math, but the preview post omitted the math entirely. Just paste it into a worksheet to convert this text mess into a mathematical one.)

## incorrect display of HTML code exported from MW

by:
I have noticed that my text that was converted from MW to HTML is not properly displayed. If you look at the end of the text, you will se the command > f:=x->piecewise(x FSeries:=FSeriesOfFunction(f,-Pi..Pi); which is not correct. The part "FSeries:=FSeriesOfFunction(f,-Pi..Pi);" is the next command. View the original worksheet via the MapleNet to see the difference. The problem is in the symbol "lower than" (which appears in definition of the piecewise continous function), because the publication system (or what) thinks that it is the begining of an unsupported HTML tag and the "tag" is removed. The solution is to substitute "lower than" for "< ;" (without the white space before the semicolon) and maybe the same with the "grater than" symbol.

## Complaints

by:
I'm in the process of manipulating Maple worksheets (both Classic .mws and Standard .mw formats) blindly from the command line. There are a surprising number of stumbling blocks in Maple that make this work difficult. While I've managed to worm my way around them one by one, I thought I'd take some time to just voice my frustration so that others are aware of these pitfalls.

I should note that I am using Maple 10.02 on a Gentoo Linux machine, feeding my commands into Maple through a standard pipe. I would update to Maple 10.04, but the updater program from the website continues to cause problems with Java. Another complaint? That might as well be...
