I resolve the surface flat grinding of a metal pieces in Mathematica, but I would like convert this program in Maple syntaxis. 

Thanks in advance!



I would like to start using maple workbook to manage my projects but i can't figure out the paths. suppose i have a workbook named: WorkBookTest.maple

and inside this i have a folder containing Data in which i have an excel workbook DataTest.xlsx

and also i have a folder containing Documents in which i have a maple worksheet

and also i have a folder containing Code in which i have a mathematica notebook Code.nb


Now inside the maple worksheet, to import the excel data i use the command: Import("this:///Data/DataTest.xlsx")

and it works

Now inside the mathematica workbook, to import the excel data i use the command: Import["this:///Data//DataTest.xlsx"]

and it fails


so if i have other program like mathematica notebook inside maple workbook that wants to call a file with data, how should i define the path?

Hello All,

What is the Maple equivalent command for $MaxNumber/$MinNumber and $MaxMachineNumber/$MinMachineNumber (these should be 10^308/10^-308) found in Mathematica.

I never asked this question before because I do *not* like comparisons between Maple and Mathematica, as I said in a post some months ago.

Best :)



I have the mathematica code given below. I am using Wolfram Mathematica Online.
I am very new to Mathematica. When I put this code, I do not get any output.
It just does not show me anything.

\[Alpha] = 3; F[s_] := Exp[-A*s^(2/\[Alpha])]; integral = Re[Assuming[{A > 0, t > 0, {t, A} \[Element] Reals}, Integrate[F[s]*Exp[s*t] /. s -> I*y, {y, 0, Infinity}]/Pi]]

Can some help me?

I hope that in the future if mapleprimes ever does another overhaul that it does NOT do what has recently been done at the mathematica forum I just came across.

Mapleprimes has endured a forum change from primes1 to primes2(current forum) and all posts/questions have for the most part remained intact, and have been repaired or fixed by the developers if pointed out .. thumbs up for Maplesoft and Mapleprimes developers for retaining all forum data.  Most posts that didn't have a home were simply relocated, but are still accessible.

In the case for mathematica, a whole student forum was removed and is being scrutinized, and decided by mathematica developers whether or not the post should be put back into the forum (currently none of the posts have been restored).  I would think that would be most dissappointing from any user standpoint. 

There are no users with 0 reputation.  It appears all users with 0 reputation and negative reputation have been erased.  One user I can not find who is or now was a legitimate user is John Mcloone an employee at Mathematica who made a post here.  I can only think during the recent spam attack that all users with 0 or negative reputation were removed.  Some of those users had legitimate questions.  Where did those users, John Mcloone and their posts go? 


     I have a list of 603 integrals that I want to evaluate. Unfortunately, I can't get Maple to do most of them. Mathematica can do some that Maple can't, and returns an answer in terms of BesselJ functions. So my question is 2-fold

1) Is there a way to make Maple do this integral?
2) If not, is there a way to efficiently convert 603 expessions to Mathematica and back?


assume(k1::real, k2::real, R::real, R>0);
a :=cos(x)*exp(I*(k1*R*sin(x)+k2*R*sin(x)-4*x))*sin(x):
int(a, x=-Pi/2..Pi/2) assuming real;



assume(k1::real, k2::real, R::real, R>0);

a :=cos(x)*exp(I*(k1*R*sin(x)+k2*R*sin(x)-4*x))*sin(x)



int(a, x=-Pi/2..Pi/2) assuming real;

int(cos(x)*exp(I*(k1*R*sin(x)+k2*R*sin(x)-4*x))*sin(x), x = -(1/2)*Pi .. (1/2)*Pi)

Mathematica 10.3.0 was announced yesterday. This is the 6th release of Mathematica 10 during 16 months. I wonder its  MathematicaFunctionData and   FindFormula . At first sight, the former is an analog of FunctionAdvisor of Maple, but the latter isn't any analog. Also compare the outputs of




>`assuming`([residue(binomial(n, k), n = -j)], [integer, j > 0]);

                residue(binomial(n, k), n = -j)
Let us wait for Maple 2016.


I am trying to use Maple 18 to do some computations with matrices over a ring of polynomials in one variable over the integers $\mathbb{Z}[x]$, or the corresponding field of fractions $\mathbb{Q}(x)$.


The matrices in question are of dimension approximately 5000 and are sparse. The algorithm requires at least as many matrix multiplications as the dimension of the space.

Doing some small examples, of dimension 674, with a laptop (i7-3520 M CPU @2.9GHz with 8GB of Ram) gave the following disappointing result:




When a colleague with access to a Mathematica license performed an identical calculation using sparse matrices in Mathematica, we found that Mathematica performed the calcuation in fractions of a second.


In small dimensional examples, constructing the matrices over the field of fractions as sparse in Maple 18 resulted in a four fold decrease in the already disappointing performance of the LinearAlgebra package in Maple 18.


Is there any way to improve the computational performance of Maple 18 for symbolic linear algebra? Alternatively, is the performance of Maple 2015 for symbolic linear algebra noticably better than Maple 18?


Thanks in advance.




Hello people

i have a quetion

what is the perposes of these softwares,maple,matlab,mathmatica and latex.

for example i listened from somewhere that matlab is best for matrices, then what are the major task of these softwares which i listed above including matlab,

how we make comparison of these softwares.



I happen to just have a look at mathematica's imagedeconvolve function .  I had a look at the Examples and saw how a very blurred image of Neil Armstrong standing on the moon with the lunar lander was deconvolved into some really amazing detail. 

I don't believe that image could deconvolve into what they show on that page, It's somewhat misleading.

The only way that deconvolved image could have such great detail is the blurred image used was most likely convolved from the detailed image.  

Hello all ,

Having read a recent post about comparing Maple and Mathematica I'd like to throw my 2 cents (FWIW).

It is *silly* (not to say stupid) to compare these two softwares.

Maple can do "things" that Mathematica can't. For examples Differential Geometry, Lie Algrebra, covariant derivative and the like.

And Mathematica Manipulate command is far better than Maple Explore (just another exemple).

I have being using Maple since Release V.2 (1992) and Mathematica since Release 1.1.a (1991).

I use both of them on a daily basis and I *LOVE* them both.

Inputs are welcome :-)

Kind regards to all,




I just started to use Maple and I have a question if there exists in it an equivalent function to Mathematica's FindInstance? In general, I have an inequality and I would like to find few first solutions to it.

Does anyone know how to using some softward convert ?  for example  I have maple code , but I want to using mathematica code .I need fast way.

In this section, we will consider several linear dynamical systems in which each mathematical model is a differential equation of second order with constant coefficients with initial conditions specifi ed in a time that we take as t = t0.

All in maple.
