Which function represent phi in 3.28.1

Hi,

I would like to ask, what is the way to use the Direct Search (or other similar package) to solve not a static optimization problem for, say f(x_1,x_2), but the dynamic one, say for f(x_1(t),x_2(t),t)?

I think there must be the way of adapting the algorithm for that.

Any ideas welcome.

Want create my own geometric distribution with rather only natural values i.e. without zero:

c:=Distribution(PDF=(t->PDF(Geometric(p),t-1)));
But such form is luck to calculate even Mean value:

simplify(Mean(c)) fails. How to apply to get even Mean(F(c)) for complicated enough F?

In which context runs subj? Why all time when i start debugging with 'stoperror' it stops at 'interface' call i.e. in debugger

interface('prettyprint')

doesn't return 3 as worksheet returns. It return interface('prettyprint') i.e. symbol.

I have a matrix with values of interest from .04<4 and I want to round all the terms that are ~10^-10 and lower to zero.  Is there an easy way to do this?  fnormal only works for lists!

The following example shows some typical computations with Householder- or reflextion matrices. Why are the second and third variants only slightly better than the first one? Could we get a real speedup without rtable/NAG/BLAS/etc. tricks?

I'm writing a maplet and I would like to put in my MathMLViewer two equations. Each equation in different line. How can I do this using MathML[Export]() while setting the value of MathMLViewer ?

As an intermediate result in a longer calculation I got the following equation:

I'm working on a project that involves solving a large system of polynomial equations using 'solve', with some inequalities of the form "a<>b" or "a<>0". Initially, I was using Maple 9.5 with great success; the machine I was using was upgraded to Maple 11, and now 'solve' struggles with problems that were previously easy (<30 seconds).

Were there any major changes in 'solve' between these two versions? (No, according to the documentation; Yes, according to the source....

So I have something like this:

> with(plots);
> with(plottools);
> with(DEtools);

what should do?

i guess to use Hn directly and use sum(Hn*z^m/m!)

is it possible in Maple?

Solve the equation (x-2)^{(25-x^2)}=1

Hi,

I have a third order system with nonconstant coefficients I would like to solve in Maple.  I have found a solution  but, I need a general solution.  I have attached the worksheet.  In the worksheet I have commented the system and the known solution.  AllCalculationsPertu.mw

Is there some way to construct the general solution from known solutions like a variation of parameters?

How to patch library maple functions locally if there any method?

Found that in

IntegralTransforms:-Tools:-SimplifyPower

in 195-196

instead of

j := evalf(j[-1][2]-1);
k := evalf(j[1][1]+1)

should be

j := evalf(t1[-1][2]-1);
k := evalf(t1[1][1]+1)
