At some point a version of the Maple Player (for the PC, rather than iPad) became available for download from its webpage.

One of those vexing things that should be easy:

I am reading in a data file using ImportMatrix. Since the file has one column with texual data I cannot use datatype=float since that bombs. I >can< ImportMatrix with datatype=string or anything.

I then extract columns using the appropriate command and want to do something numeric with them (only with those columns that have correct floating point numbers). That fails since my data are now not floats (even when using anything...

Hi,
How do I complete the integral below? I'm not sure what the resulting function looks like, but it will be a function of n where epsilon is a real constant. My ultimate goal is to graph the resulting function where epsilon is equal to -0.4.

Thank you.

Hi, 

in my programm I've got a maplet with 6 CheckBoxes, but I can't manage to get the true/false-values in a list to use them. I think I should define a list, I tried:

BoxRow(...

   GridLayout([

      [CheckBox['CB1](), "Box1"],

      ....for all 6 boxes...

])),

lstW:=['CB1','CB2',...for all 6 boxes];

But all I get is: Error, `:=`unexpected. 

Try to run the following:

>restart;
>d := conjugate(u)*conjugate(y)+conjugate(v)*conjugate(x);
>z := conjugate(f)/d+conjugate(G)*w*conjugate(w)*conjugate(y)/d;
>z2 := simplify(z);

and you will get correct answer

hi

I have an unkhown function as f(r) which i want to solve it at the end of calculation. How can i define it in beggining?

I created a Maplet that calculates ODE (Ordinary Differential Equations) however I would like to create a button that can allow printing on paper

Everyone knows that Maple combines a smart user interface with a highly sophisticated mathematical engine, where common tasks are performed quickly and seamlessly with point, click and drag operations. Of equal importance, however, is the fact that Maple is also backed by a comprehensive programming language. Also called "Maple", this language combines elements from procedural languages (like C), functional languages (like Lisp) as well as object oriented languages (like C++...

i confused for finding a very special command that can join a "set of values" to a "set of indices " ?

also i can't use the map command for this ( guide ? )

like this :

{(1,1),(1,2),(2,1),(2,2)}

{1,2,3,4}

i want to join the two sets to form a complet set of equations index :

{(1,1)=1,(1,2)=2,(2,1)=3,(2,2)=4}

since this is just a simple example , but i need an efficent way for doing it in large size data (image processing)

appreciate for answering !

For example, fill in the follwing blanks with 1~9 numbers to make it as an identity, the numbers are MutuallyExclusive.
()/()+()/()+()/()+()/()=()
Thank you very much for any method.

Please could you please help me finding closed expression for the following double integral

restart;

with(LinearAlgebra);

rho := .25; sigma := .1; SNR := 25;                                                                    

 a := (32*12)*Pi*sqrt(1-rho^2...

Hi, i am new to Maple. I was trying to solve some problem and came up with the following difficulty:

When i give input

a_i=(1+k_i)/(1-k_i);

and then do a_1 it gives the proper output as 

(1+k1)/(1-k1);

But whenever i try to do

a_i,j=(k_i-k_j)

I am using an old package, Janet, I got from http://wwwb.math.rwth-aachen.de/Janet/janet.html with Maple 16.

I changed the libname to point to the directory where the package files are.

Few days ago I was able to call help(Janet); without any problems but now everytime I try to call help(Janet)

Maple front-end loses connection to the ihe Maple kernel.

The package loads fine...

Hello,

Please, i want to resolve a non linear eaquation with Lagrange multiplier with 4 variables.

But it dosen't work.

Can you help me in this.

Thank you

Good afternoon everybody,

I have a question regarding the command matrixplot. I wrote a programm with two input parameters:

v=[seq(0.29+i/100,i=1..8)]

k=[seq(2*i,i=1..50)]*0.5*10^(-15)

and I get a matrix [8x50] that I want plot.

The problem with matrixplot is that I get in the axis the number of rows and columns but I would like to put the value of v and k instead of the row/column's number. Someone knows how I can change that?
