Hi, I have a 1x1 matrix. I would like to use the value in it but not as a matrix, any idea how I should take away the matrix and just take the inner matrix? Please help. Thanks.

For example instead of [8x+3], i would like it to be just 8x+3

Hello,

I would like to do the following procedure from a basic concept, but I can't figure out what I'm doing wrong (sorry for that, I'm a beginner). I have tried to look up some more information about procedures on the Help menu with no success. Here you have what I'm planning to do:

Considering the following function (which approximates the cosine function):

aprcos:=(x,n)->add((-1)^i*(x^(2*i)/(2*i)!),i=0..n)

I would like...

I have simplified a fairly large expression derived by Maple and am chacking to see if the two expressions are the same.  Previously, when I did this, the result was pretty straightforward: when the output was 0 = 0, the expressions were the same; however, now when Maple simplifies the expression I can sometimes use a combination of the simplify, factor, expand, collect, and combine functions to get it to spit out 0 = 0, but sometimes I can't.  Here is an example which shows the problem.

how do i write a command of a length of an array?

for example, c:=[1 3 5 7 8 2 1]..the length is 7 right? so how do i write the command..

it's a pleasure if any can help..

Is it possible to insert a hyperlink to a pdf file ? I use links to other Maple worksheets and internet URLs, but cannot seem to find a way to create a link to a local pdf file. Thanks for any help.

Happy Holidays !

I'd like to be able to get a quicker low accuracy computation of the argument of the complex-valued JacobiTheta1 function.

I only need as much accuracy as to get a decent plot, which means... I don't know... about 1e-3 relative accuracy?

If I can get a formula or approach that is "evalhf'able" then I can construct a procedure which does this action and writes results inplace to a float[8] Matrix.

The naive approach in the code below takes about 6min...

Hi all, I am having two simultaneous equations , i dont know how to solve these two equations, any one help to solve these equations..

Im knowing the approximate/accurate answer for the equations,
These are the values for my equations

alpha=1.53222, beta= -0.555345, kappa= -0.399943,

Hello,

I'm trying to plot the function (5*x)/(x^2-4) highlighting all of its characteristics (maxima, minima, convexity, concavity...). I would like to plot this function in different colors in accordance with the different intervals of concavity and convexity. In order to do this, I have tried to use the piecewise function, as shown on another question (http://www.mapleprimes.com/posts/43593-Piecewise--Color). However, I feel I haven't understood quite well how it works, as I can't figure out how to write the intervals... I don't know if I should show you my attempt, but I think it's quite ridiculous (I just have tried to adapt it to the example shown on the question I have read).

Thank you very much for your attention!

Have a nice day!

Would you please send me the numerical laplace inversion code of "de Hoog" 1982?

i use previous post link to derive again for weibull, the final integration seems can not be integrated,

any things need to notice?

Weibull
WeibullDist := (η/rho)*((x/rho)^(η-1))*exp(-((x/rho)^η));
WeibullDist := 1-summation((η/rho)*((x/rho)^(η-1))*exp(-((x/rho)^η)),x=0..k-1);
WeibullDist := int((η*z)*(((k-1)*z)^(η-1))*exp(-(((k-1)*z)^η)),z=0..1/rho);
WeibullDist := int((η*z)*(((k-1)*z)^(η-1))*exp(-(((k-1)*z)^η)),z=0..1/rho);

svp. Je suis débutant en Maple et je souhaite que vous m'aidiez à réaliser une courbe avec maple étant donné un ensemble de points, et non pas une fonction. Comment faire? merci.
