Greetings All
I'm trying to make/graph a BIPHASIC PULSE in maple 10
example: http://www.daqarta.com/stim3a-d.htm#dd0b
Can someone point me in the right direction.

This return unevaluated :
int(1/u/exp(u)^2*exp(-1/4*u^2),u = 0 .. x);
Would Maple give an explicit answer ?

Does Maple have a method for integrating a function (1-dimensional)
over a given and non equally spaced list of points (say: measured
data) - like Simpson's method?
ApproximateInt(fct(x), x=a..b, method=simpson, partition=L) does

hello mapliens...
is there something like plots[inequal] for 3D graphs?
i would like to plot
x <= 1000, x>0

Consider:
restart;
eq1 := Int(a*f(x) + b*g(x) + h(x), x=0..1) = 0:
eq2 := Int(a*u(x) + b*v(x) + w(x), x=0..1) = 0:

Hello Group,
how can we collect square root within Maple 10 ?
I am asking because
collect(<some formula>,[sqrt])

I need to calculate the eigenvectors of a hermitian matrix with
two-fold degenerate eigenvalues. Could it be that the eigenvectors
calculated by Maple in this case are not necessarily orthogonal but
only linearly independent? -- The help pages do not talk about this.

I am using Maple 10.03, classical interface.
I've written some code. I noticed that when I run it, the plot generated at
the end looks a little different sometimes.
I do restart at the start of each run. So this means everything is

I'm a relatively infrequent user of Maple (ver.  V R4), and have not pre-
viously used any complicated procedures.  But now I need to define an array
of functions, and so far have been unsuccessful.  Earlier I've defined an
analytic function

With animate we can have a background-curve.
Instead of the background-curve I want to use a picture (jpg or gif).
Is this possible?
I appreciate any help.

hi;
I thought in Maple an actual argument is evaluated before the call to a
proc() and the value of the actual is what become the formal parameter.
That is why the following gives an error:

diff(hypergeom([1, 3/2+x],[2+x, 1+x],1),x);

int(1/u*erf(u),u)

hello mapliens,
when A and B are matrix, products are defined and printed as A &* B or
multiply(A,B)... not very pretty...
i have to define my equations twice : one to compute, one for the

I'm trying to get a handle on what Maple does with some matrix
operations.
I wasn't able to figure it out by web or newsgroups search so maybe you
can help.
