hello,

after defining N_1 N_2 and N_3 with long numbers, and defining M by N_1*N_2*N_3 i tried to step backwards.

By entering something like: M/N_1 (what is exactly like N_2*N_3) it does not show me full numbers, but instead 1/something*M.

After refreshing M and afterwards refreshing M/N_1 it totally worked out and showed me the product of N_2*N_3

Now my question is: how can i prevent this odd display format without refreshing everytime? (i tried...

i would like to find all modules in the complex
for example

0 -> A -> B -> C -> 0

would like to find B and C if know A

Hi

I want to solve a set of two ordinary differential equations by means of Maple. I can not unfortunately perform it as a non-numeric method. It is worth mentioning that by the following commands, Maple returns a solution presented as a DESol form, which is not useful for me. Note that functions C2_U0[i](theta) and C2_V0[i](theta) are obtained in terms of  C1_U0[i](theta) and C1_V0[i](theta) by using boundary conditions bc1_U0[i] and bc1_V0[i...

When exporting plots some labels are occasionally cropped. This is true when exporting via the context menu or with plotsetup('gif', etc.) for instance (plotsetup also drops the third label in 3D plots, the context menu keeps it).

I discovered that scaling the plot from the context menu can help: is there a programmatic way to control the plot scale?

From the context menu: Manipulator -> Scale, the plot can be rescaled to ensure that all...

I am trying to solve the following bvp:

with*plots

Eq[1] := diff(f(eta), `$`(eta, 3))+3*f(eta)*(diff(f(eta), `$`(eta, 2)))-2*(diff(f(eta), eta))^2+theta(eta)

Eq[2] := diff(theta(eta), `$`(eta, 2))+3*Pr*f(eta)*(diff(theta(eta), eta))

Eq[3] := diff(phi(eta), `$`(eta, 2))+3*Sc*f(eta)*(diff(phi(eta), eta))-kappa*Sc*(phi(eta)*(diff(theta(eta), `$`(eta, 2)))+(diff(theta(eta), eta))*(diff(phi(eta), eta)))

BCs := [f(0), (D(f))(0), ((D@@2)(f)...

I realize that Maple itself does everything but I would like a simpler cheaper solution for a number of computers in my classroom.  Multiple licenses of Maple is not an option.

Interesting behavior!!

Hello!

I have a strange issue:   I have a procedure with signum, square roots, I and float numbers. First I optimize it and then compile.  (or just run compile with option optimize=true).  As a result I get a error:

Error, (in TargetLanguageTools:-GetExprType) Analysis is not a command in the _EnvCGEngine package

Trying to understand, what is happening, I manually copy-paste the optimised procedure to the argument of compile. Then it works!!!

Hi,

Is there a way to generate Java or C code to implement a general nth order linear ordinary differential equation?

I am looking to be able to send the coefficients and have it compute the time waveform given initial conditions.

Regards.

I wish to use the 'Numeric Formatting' feature on some results in Maple, to show the correct significant figures in the results. But when I apply Numeric Formatting to any result, the decimal seperator changes from the usual dot (.) to a comma (,). How can I keep the dot as decimal seperator while applying the correct significant figures?

Thanks. 

Hi, I would like to label curves on a plot but using horizontal text looks really bad.  I would like to use verical text labels or even text labels that follow the curves.  It this possible in Maple?  I have tried rotate with textplot but that only rotates the point and not the text.  Any ideas would be great! Thanks.

With the command, subpicture,I take the portion of it that interests me.
How I manage to include this sub-image in another image (img)?
