Dear All

Hi

I have a question about Maple 16.

Does Maple 16 is able to use several cores in multi-cores system?

Does Maple 16 is able to execute some common commands such as int, diff, dsolve and solve with capabilities of a multi-cores system?

Hello,

I have to design a wheeled mobile robot for my bachelor-thesis. the robot should be controlled in Simulink. Therefore, I have to use the Simulink Component Block Generator. Outputs are: yaw angle/rate, absolute position in x/z and its derivatives, wheel angle and its derivative,steering angle. Inputs are one torque for steering and one torque for actuatuating for each wheel. -->6 torques (3 wheels). When I click on the "Generate and Compile...

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...

How to find the volume of the intersection of the sphere {(x, y, z): x^2+y^2+z^2 <= R^2 } and
the set {(x, y, z): |x| <= a, |y| <= a } under the assumptions R > a*sqrt(2) and a > 0?

I encountered a problem with a simple subs in Maple 15.01:

Q:=1/(a*l);

subs(a*l=t,Q);

This fails to perform the substitution and gives 1/(a*l) instead of 1/t.

However, it seems to work in certain form, for example:

Q:=exp(a*l);

subs(a*l=t,Q);

produces exp(t) correctly.

Furthermore,

Q:=1/(a*l)*exp(a*l);

subs(a*l=t,Q);

gives exp(t)/(a*l). Strangely, the substitution in the exponential is correct...

I am trying to maximize a non-linear function f with respect to variables {a,b}.

Could any one suggest a smarter way of entering this into Maple please, as I am not able to get an answer.Thank you.

The function (shown below) also has the parameters {c,H} in it and I have the constraint:

CONSTRAINT:______________0

My Function f:

(256 a^4 (4 c - H) + (1604 c - 10385 H) H^4 -
   60 b^3 H (56 c + 177 H) + 6 b^2 H^2 (-708 c + 1663 H) +

Hi,

I'm trying to use powsolve to give me the power series of a differential equation. It's been working wonderfully, afaik, but once I put in exp(x) it refuses to run. Here's my code:

 >with(powseries);

>a := powsolve(diff(y(x), x, x)+y*exp(x) = 0, y(0) = 1, (D(y))(0) = 2); tpsform(a, x)

and the error I'm getting:

Error, (in powseries:-powsolve) final value in for loop must be numeric or character

> restart; with(DEtools);
> ED1 := diff(y(x), x) = sen(y)+cos(x);
print(`output redirected...`); # input placeholder
                    d                        
                   --- y(x) = sen(y) + cos(x)
                    dx                       
> dfieldplot(ED1, y(x), x = 0, y = 0, title = `Ejemplo 1`, color = sen(y)+cos(x), arrows = almit, title = figura*(diff(1, x)));
%;
Error, (in DEtools/dfieldplot) invalid range for independent variable

See attached.  I have stared at this long enough to the point I need some FRESH eyes on this.  Why does MAPLE return FALSE on the last 2 statements

Solve the equation y"-4y=lnx ?

Hello!

if anyone can help ill be greatful!.

i have his equation:

eq1:=(8/x)=tan(7*x/50)

of course  there are infinite analitical solutions....   solution = F(x)+Pi*n, n=1....infinity

what i want to do, is to define N. and then,  to put the first N solutions of the equation into a Vector called X,

so X[1]=F(x)+1*Pi

X[2]=F(x)+2*Pi

...

X[N]=F(x)+N*Pi

can someone help?

Hi,

How can we re-initialize a multi-body system, for example a three link pendulum, based on measurements obtained from various sensors? Can we generate a modelica custom component which has inputs from various sensors and the output is the re-initialized states for the multi-body system?

Thanks for your help....

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...
