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...

Hi there,

I would like to know if it is possible to get the results of a simulation as a table with the values of the output variable as numbers instead a graphic. for example:

time     temperature

0.1s     300k

0.2s     305K

.......

Thanks

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 have a module which is an argument to a procedure.

When I "trace" this procedure, the entire module is  printed (as it should).

Is there a way to NOT print the contents of the passed module? It is annoying when debugging.

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.

A simple timing program

st:=time():
for i to 35 do
  i;
end do;
time()-st;

On M16 seems to display after 7 seconds, the time reads 0.010
On M12 it displays in roughly 2 seconds with the time as 0.170

It is physically longer with M16.  Do others get the same results?

**edit add**
No comments?  I should add that it is a laptop 1.4Ghz single core.  Not that it matters but maybe M16 is set up to work more efficiently...

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)?

Preview(correctedT)

imgs := GetSubImage(correctedT, 100, 125, 20, 120)
Preview(imgs)

I’ve created a basic model of a two-lane road.

i am looking for a command adjoint a ODE, to check whether my understanding of adjoint correct or not, when i find one example different from my understanding as follows

u*diff(Y,t) - diff(U,t) + diff(y,t)*U = 0 where uppercase and lowercase are different

why after adjoint is

Y -> -u*diff(lambda,t) - diff(u,t)*lambda = miu1
U -> diff(lambda,t) + diff(y,t)*lambda = miu2

why not

Y -> u*diff(lambda,t) = miu1
U -> -diff(lambda,t) + diff(y,t)*lambda = miu2
