I've got Maple 2017 linked to MATLAB R2017a but I can't get MATLAB R2017a linked to Maple 2017.

I've got MATLAB R2016b linked to Maple 2017.

Any ideas? (Or do I just need to wait for an update?)

Hello guys!

Could you tell me what are the state-of-the-art algorithms to compute Hermite and Smith normal forms (well or just Hermite since the later can be computed by applying Hermite twice)? I am interested in these algorihtms which outputs also the respective unimodular matrices.

hello...i have a problem with this program.

I want to save the result(y,u(y)) in a text or another format file, but I encounter with this error message:

Error, (in fprintf) number expected for floating point formatBVP.mw

please help me

thanks

According to the help page:
interface(displayprecision=n)
sets the number of decimal places to be displayed to n.
But this is true only if interface(typesetting=extended).
For interface(typesetting=standard),  n represents the number of decimal places after the decimal point.
Is there any reason for this decision?

restart;
x:=123.456789012345:
interface(displayprecision=4):
interface(typesetting=standard): x;
                        123.4568
interface(typesetting=extended): x;
                        123.5

I'm trying to calculate forces between particles. I defined all my variables and the equation for force, but when I plug it all in, it gives me 0 when I know for a fact it's not 0. I should be getting something like f₁₂=-0.4, f₁₃=-0.24, and f₂₃=-0.5.

Basically I defined variables like x₁,y₁, m₁ , etc. and made my force equation f_ij with all variables having appropriate i and j subscripts.

hello. i want to write this function with  "for"loop. but i don't know

Hello!
Used PolyhedralSets for plotting.
At the moment there are a number of questions in the construction of graphs:
How to adjust the rotation of this figure around the z axis?
How to make, what color of a figure received in a cut would be much darker or Darker color?

with(PolyhedralSets);
P1 := PolyhedralSet({-x-20 <= 0, -x-20 <= 20-y, -x-20 <= -(1/2)*y, -x-20 <= -z, -x-20 <= -(x+y)*(1/2), -x-20 <= -(y+z)*(1/2)});
Plot(P1, axes = normal, view = [-40 .. 40, -40 .. 40, -40 .. 40], orientation = [30, -30, -60], color = blue, thickness = 2);
Plot(P1, axes = normal, view = [-40 .. 40, -40 .. 40, -40 .. -40], orientation = [0, 0, 0], color = blue, thickness = 2)

I'm trying to obtain integral of Planck radiation law in Maple:

with this command:

f := (2*h*(c)^(2))/((x)^(5))*(1)/(exp((h*c)/(x*k*T))-1);
int(f,x=0..infinity);

but I get some terrible limit that cannot be solved instead of the correct result:

How to obtain correct integral?

I followed the basic example RLS circuit first. It worked out well for R = 24 ohms, L = 160 mHand C = 200 microF. Signal is step input h = 1 and  t₀ =  0.1 s. Simulation t_d = 0.5 s

When I extended it for DC motor, the output for torque (tou) and speed (w) not plotted for h = 1  t₀ =  1s and simulation td = 5 s for the same parameters as above the output required (shown in manual) is not coming. Is it because default values shown were different? Then how do i change? I am enclosing the file for view and help.

How to label in inline math mode. I tried labels = ['theta', Typesetting:-Typeset(cos(1/theta)/sqrt(1-theta^2))] which gives a big expression on Y axis spreaded in two lines. But i want to label one line as in latex $\cos(1/\theta)/sqrt(1-\theta^2))$ . Is there a way to do it ?

the program shows that the error please verify it sirprogram11.mw

Hello,

I have an industrial robot model and I need to define constraints for the revolute joints. For example, R2 joint is only allowed to move between -165 to 165 degrees. Could you please tell me how I can impose these constraints?

Thank you.

what's the problem with PDE below? tnx for help

Hi

I have two equations as follows:

The goal is finding the parameter 'phi'. This parameter is a positive real numeric constant.

I uploaded two files that they are included two methods to solve the problem.

1.mw

2.mw

Is method in the first file mathematically logical? If it is a correct method, why the command fsolve dosent work?

In file 2, we have 2 equations with further indeterminantes. The constant 'phi' must be minimum possible amount. How we can use the commands like the Minimize in Optimization? Please hint me.

Moreover, if there is a method to solve this problem please help me to know.

Thank you very much 

I want to set the position of the legend inside the figure window for example say top right in the figure window. Maple chose the legend to be at right, left, top, bottom outside the figure window. How can I place the legend of my own wish?

thanks,
