Is there any way to detect programmatically that a WARNING has been issued? A method that converts WARNINGs to errors would be acceptable.

Hi all,

restart:
a:=<1,2;3,4>;
whattype(a);
b:=Matrix(2,2,[1,2,3,4]);
whattype(b);
evalb(a=b);

Is there any real difference between these two methods of creathing matrices?

How do I check if two matrices are equal?

Thanks,

Casper

How do I copy Maple input without any modifications?

Here is my problem:Consider the MAPLE input below (Copy Example). Copy and paste results in:

restart; with(VectorCalculus); SpaceCurve(`<,>`(VectorCalculus:-`*`(2, cos(t)), VectorCalculus:-`*`(2, sin(t)), t), t = 0 .. VectorCalculus:-`*`(2, Pi), axes = boxed, thickness = 2, color = black)

which is not the same as the input. I need the unmodified Maple input for a documentation, which is published...

After viewing the table in print preview I realized that the table goes into the second page. I want to reduce the height of the table so that it fits in one page. How is that possible?

By moving the cursor to the edges of the table, I realized that it would allow to me to adjust the width of the table but not the height. The table has about 12 rows. 9 of them fit in one page, but 3 of them go into the next page. I want to shorten the height of the table so that the...

Can you help me, why I get such error,

what is the maple coding for the function, f(t)=-1-(epsilon)v(t) with the initial condition v(0)=1 for the 10 term?

i had did it but i don't know how to come up with the expansion series in the maple coding

i'm trying to solve this parametric parametequation(a1,a2 & l are parameters and n is my variable): 

a2*(l^(2*n)-1)-2*(a1+n*a2)*(l^n)*log(l)=0

when i try to solve this parametric equation, maple return a RootOf term and when i try to see the values of this RootOf by Allvalues, again return a RootOf, but when i replace the parameters by numbers(like a1=400, a2=25 & l=3.2), maple return a unique n. 

Given points on the surface of cylinder, how to find a point on the axis of the cylinder, axis's vector and radius of the cylinder?

I am attempting to apply some routine tests to determine the convergence of series with positive terms. I have run into a little difficulty with the root test. I am using surd( ) as shown below, but Maple will not give the exact value, which in my example, should be exp(6). Why is this happening and is there a way to get the root test to work?

Thanks!

How can I successfully input the following problem and be able to solve it. I have been trying with no luck. Please advise. Problem: Find the mass of a planet of radius (R), if its density at each radius (p) is δ= (p+1)/p. Notice the infinite density at its center, but finite mass M=∫∫∫δ dV. Here p is radius not density. Ok, I have the answer but have not been able to get with maple. Answer: Mass=∫∫∫psin(Φ)(p+1)dpdΦdΘ= 4/3∏R^3+2∏R^2....

How can I have Maple construct a time sequence?

My problem states 70 observations, but if you can assist me with 10, Ill figure out hte rest. so pretend there are only 10 observations... 140,159,138,102,84,126,147,126,103,92... Thank you to anyone who can help!

Hi folks, I am solving a boundary value problem numerically using dsolve. I would like to pass the resulting solution (which I gather is really a procedure) back into another differential equation as a coefficient.

M:=x(xi)^2+1:

ode1:=diff(M*diff(x(xi),xi),xi)-0*x(xi)=0:

ics:=x(0)=0,x(1)=1:

sol1:=dsolve({ode1,ics},numeric,output=listprocedure):

y_sol1:=sol1[2]:

y_sol1:=rhs(y_sol1):

% I could then plot the solution using 

Hi Everyone:)

I'm doing a mini project at the moment and I'm pretty stuck with how to go about something on Maple...

My aim is to get the catenoid from an initial cylinder by use of an iterative method.

To find the minimal surface r=g(θ,z) - the catenoid - I want to minimise the Dirichlet integral (in cylindrical polar coordinates)

I'd like to be able to plot a function that not only has a range for the dependent variable(s) but also for any "variable constants" that may be in the expression.

For example, if I wanted to plot the following expression :

                    y = A sin(wx + c)

and also to explore its behaviour over the following ranges for A, w and c :
