I am trying to evaluate a limit involving two variables z and t, that
show up in combinations like erf(t*z) and exp(t*z). The variable t
goes to -infinity, and z remains finite, so we know the limits in
these functions. How can I get Maple to calculate these limits?

The explanation page for ?type  lists "array" as one of Maples's types, yet
that seems inconsistent with the output from simple commands such as
v:=array(1..3,[5,6,7]);
     v:= [5,6,7]

I'd like to know if there's something like a subs equivalent for
matrices. Taking for example
S:=Matrix([[0,0,-1,-1,-1,1],[0,0,1,1,-1,1],[-1,1,0,0,-1,-1],[-1,1,0,0,1,1],[-1,-1,-1,1,0,0],[1,1,-1,1,0,0]]);
then

Am building an array of functions for Lagrange polynomial
interpolation of a set of points
(lsubj[i] in the code that follows).
Have what appears to be a working model; but have kind of a clunky way

I am looking for effective method how to analytically evaluate
multidimensional integral of the positive integer power of multivariate
polynomial over the hypercube, where power of the polynomial and number or
variables (dimension) may be high.

Given a connected 2D curve, such as the graph of a function either in
Cartesian or polar coordinates, is there any quick way to use this curve's
definition and add a slight modification to make the curve non-differentiable
at a finite number of points?

I have a single, first order differential equation in the unknown x(t):
  dx/dt = H(x),
  x(0) = 0,
where H is given as a proc.  Here is a sample H:

Dear folks.
i am writing a script to work with a bunch of maple worksheets in unix

made big advances with Maple over the last few weeks. such a great
tool. can anybody give me some advice on this problem and how to
produce a symbolic answer?? If W is a function of Q[i] and P in that

Dear Group
I am quite a newbie using maple (v10). I have looked for a solution to
the following
problem in this group and I haven't been able to find a solution.

Maple's msolve(eqns, 2) is a great tool.
Say I have a set of linear equations with far too many unknowns.  I can
solve them over mod 2 and Maple will return thousands of solutions
(_MaxSolns is modified). However, I just want the sparsest solution (the

In Matlab, if there is a matrix A such as
    1     0     0
    0     2     3
    0     0     1

May be this is a native question. But I am running both maple and
matlab on the same PC. Matlab uses double floating by default (8
bytes), and I expected Maple to give me the exact same numerical
values from this simple

I have a small question relevant to solve function. I would like to
receive a solution which will be independent on some variable which is
of course in my equation.
For example

I understand that there are several versions of maple available.
Which do you recommend and why?  Thanks.
