Does Maple 9.0 work with Mac OS 10.4?
Does anyone else have trouble with Compiler:-Compile on a Mac?
I have gcc 4.0 installed on Mac OS X 10.4.2.
For example for,
p := proc( x :: float ) :: float; 2.3 * x end:
cp := Compiler:-Compile( p ):
cp( 1.1 );
I get the message:
Error, (in LinkDSO) linker exited with nonzero status 256: /usr/bin/ld: can't locate file for: -lcc_dynamic
But on my home Mac, which I think is configured in exactly the same way, the same commands work!
After a lucky google search I found a reference to the problem. A symbolic link is removed by the installation of gcc 4.0. Running Disk Utility to fix permissions repairs the link, and now Compiler:-Compile works!
I am using Maple 10. In the tools menu I click "check for updates" and then go through the procedure of updating. In the end I get the dialog box "Update was unsuccessful because of the following reasons" (1) You might not be logged in as administrator .I am logged in as administrator as a matter of fact. (2) You might not have enough disk space. I have plenty of disk space left.
I have no clue as to how to get around this situaton. Please help.
Once again Maple has screwed things up in a new version. The material in my book, Differential Geometry and its Applications, on unduloids using elliptic functions doesn't give the correct pictures in Maple 10. Maple 9.5 worked fine. Also, something has been done to the simplification routines. In Maple 9.5, the metric and second fundamental form for unduloids are simplified to a point where they can be easily identified. In Maple 10, all that you get is a huge mess. At the Maple Workshop in 2002, I asked about these issues that have cropped up before (the worst being the transition from the wonderful Maple 4 to the horrendous Maple 5).
how can I plot a vertical line? for example x=5, starting from y=0 to y=10.
When i use Maple to solve polynomial for two times. first the order arrange
from max to min. second arrange from min to max. I want to know what the
Maple procedure calculate to show?
I know I can plot y=x^2 by using command like plot(x^2, x=-2..2);.
In this example we have an explicit expression of y. What if we cannot find
an explicit expression of y? For example, suppose we do not want to find
an explicit expression of y in equation x^2+y^2=1, then how can we plot this
by the way, what's the difference between forum and blog here?
i have a bunch of commands as follows, seperated by shift+return. after the last
command, a return ofcourse. Then I execute these commands by a return.
it will give a result, but next time I enter return again, it gives
another result. What's wrong?
You can test in maple. I will change
value of x. when x=400, command
tau := fsolve(S(t)=c,t, 0..infinity);
returns no solution. but start from x=500 and larger, it has solution.
The problem is, when I change x, the value of tau doesn't change
(sometimes it may change, but sometimes it wouldn't). I don't know if
it is because the assignment of S,H,F.
Can somebody provide me with code or hints how to get function values in tabular form?
what is the meaning of type operator :: and module memeber selector :-? the maple help doesn't explain to me..
I'm frustrated by some ODE problems. sorry the form is a little bit complex:
solution := dsolve([diff(s(t),t) = A - A * rho^((1 - r^(theta * t)) * x) - v, diff(f(t),t)=((c - s(t)) / l) * m + x, diff(h(t),t) = x, f(0) = 0, s(0) = 0, h(0) = 0], numeric);
for this problem no closed-form, only numerical solution can be found.
I have following questions:
(1) why cannot I evaluate the value of f(t) at t=5 by using f(5)?
(2) For each fixed x, there are curves s(t), f(t), and h(t). Given s(tau) = c, I want to find f(tau)=?. How can I do that? Do I need to find tau first, then find f(tau)? How?
You may have noticed that we've introduced prizes to get people more involved ... bribery is not beyond this crew to make this site successful.
Chi^2 calculations above some "size" or "complexity", using Maple 9.5 and Global Optimization Toolbox (GOT), may produce after some time of calculation error messages like:
"Execution stopped: stack limit reached.
The kernel has been shut down. Further computation cannot be performed."
Seeking workarounds, I have looked for information at ?kernelopts for kernelopts(stacklimit), but it was not very useful:
"Limits may be raised or lowered. Maple limits may not be raised above any system defined hard limits. "
A question was asked in the forums about series tests
. I saw that this would also make an excellent weblog entry as well.
In answer to the questions: How can I get Maple to determine if a series converges or diverges? and How can I obtain the general representation of a formal power series for a function? I offer the following advice:
