Hello. I wanted to solve a parametric 16*16 determinant. My first question is, whether or not it can be solved?! after that when I tried to open my work in progress I got the following message: "
There were problems during the loading process. Your worksheet may be incomplete". Could someone help me recorver my work? Thanks in advance.

Hello,

we have to create program which shows chemical concentration changes, but this concentration depends on time and distance along the longitudinal axis. So we have to put numbers into the left side 41x41 matrix from 3 equations:

A:=1, B:=1,E:=0.2, Δx:=0.25,Δt:=0.025.


first when i=0;

Hi, I have a 18x18 matrix called Lambda.

I'm trying to get NewLambda which consist of "(Lambda(1,1)-Lambda(2,2))/2", "(Lambda(2,2)-Lambda(3,3))/2", ....,"(Lambda(17,17)-Lambda(18,18))/2".

Here is what I wrote :

for i from 1 to 17 do
for j from 2 to 18 do
NewLambda:=((Lambda(i,i)-Lambda(j,j))/2;
end do
end do

But it doesn't show me the NewLambda. Please help. Thanks

I want to omit the independent variable

for example:

> alias(f = f(x+y, z+y));
print(`output redirected...`); # input placeholder
                               f
> f1 := z = f(x+y, z+y);
print(`output redirected...`); # input placeholder
       ...

How to edit the tex generated by the maple:Put the one equation into several rows

For example

This code p57.txt  can get the below picture

But what I want is

Hello everyone.

an equation or a table can have a label and can be later referred to by using insert->label. Can we do the same for inserted images? Like Figure 1, etc.... A workaround is to insert the image in a 1x1 table and reformat the caption. But I am not sure that's the ultimate solution.

Another related question: can an equation that is just in the 2D math mode that is not meant for execution get a dummy label like (*) or (**) or something like that?

Based on the title, once again I'll mention that the programm that I have been made by using

Maple14 could not run faster.

The function of Maple should be running effectively compared to others.

Hereby, I'll attach the programm for your further action.

That's all, thank you.

Does anyone know how to switch a joint between having a prescribed motion driver and acting as a passive joint? More specifically, I am building a bed of spring to serve as a model for haptic feedback on a Phantom Omni device. Therefore, I need to read the position of the device (which is not a problem) and then based on the position of the device calculate a force to feed back to the device.

Consider the simplified example below. In one situation I may need to give...

The fourier transform of a signal results in an answer with Real and Imaginary parts.

When I want to plot those results, is it correct that I need to take sqrt(Re^2 + Im^2)  ? 

However, if I just plot the Real parts of the answer why is that not correct?  Of course half the answer is missing, the imaginary part? but since it's imaginary it's not really that real and so why should it be included? 

Can someone shed some quick light on that subject for me? 

Dear All,

Further to my previous question on this forum "How to write data from a matrix while choosing the format?", I would like to update it by adding a complex number. What is the easiest way to deal with that?

Here is the file (that does not compile): writedataMatrix.mw

> driver := proc () local A, B, x, f, g, i, j, format, fd:

A := Matrix(3, 3):
f := 1-2*I:
g := evalf(sin((1/5)*Pi)):

Dear Maple Users

Let the density of electronic states be denoted

Hello all together,

defined is a curve C by the function:

x^(2/3)+y^(2/3)=a^(2/3)

Now i have to convert the description of the curve in the parametric representation and plot the graph.

My problem is, how i should handle the a in the function?

Thank you very much,

Josef

Hi,

i have a question concerning dsolve. I think i typed two identical lines however maple just seems to accept one of these. I am slightly confused. Any suggestions about what might have gone wrong here?

Best regards

i creat an animation in maple , and want to export it then use it in other presentation, such as word or powerpoint.

i try to save the animation, but fail, it is only one static picture, so how can i export it dymaticlally.
