I have a module with an exported procedure defined by
, like this:
loadtest := module()
This works if I put the code above into a .mpl file, and use
to load it. The problem is that I would like to save this module to a maple library:
> map( march, [ 'gc', 'reindex', 'pack' ], savelibname ):
When I try to use this newly created library after restarting maple the following happens:
| || ||[||3 2 1 -2 -1 -4||]|
| ||CALL_EXTERNAL(||[|| ||]||)|
| || ||[||1 0 1 0 -1 0||]|
in Maple 9.5 I need to generate two Vectors of random generated numbers from a normal distribution with a certain correlation. The correlation should be an input factor.
Does anyone know how to do that?
Hello everyone, my first post here.
I'm studying mechatronic engineering at university so Maple is somewhat of a godsend.
I got Maple 9.5 some years ago and it worked perfectly. But sometime last year it started going wrong. Whenever I tried to start standard maple it would give me some cryptic errors and refused to start. I had to resort to using Maple classic worksheet and it works just fine. Try as I might I could not discern the cause of my problems. I tried disabling my firewall and a number of other suggested fixes, none of which helped.
Recently I was given Maple 10.0 and I thought installing it might fix my problems. I wasn't so lucky. I get essentially the exact same error when attempting to start Maple 10.0:
The help page ?UndocumentedNames lists a few of the undocumented procedures in Maple. For example:
inner - computes the inner product (dot product) of two lists
MorrBrilCull - subroutine used by ifactor
evalgf1 - used by `mod/Gcd`
Of course, there are big differences in dsolve and dsolve numeric. But also there is a difference that is subtle. It would be nice if this subtle one were not there. It may be that there is an easy work-around. Of course, the complication that is at the root of the problem may not be subtle at all.
Look at the results of these two situations.
Tst0:= 0.5, 27.1, 0.1, 0.2, 24.0;
tst0:= beta=Tst0, lambda=Tst0, sigma=Tst0, P=Tst0, M=Tst0;
eval(%,evalf([tst0])); subs(z=0.1, %);
and using evalf(myTerm) I get .9981665521 while evalhf(myTerm) gives me
Error, remember tables are not supported in evalhf
What happens here?
Similarly to Binary Arithmetic
, Octal Arithmetic can be done using following module,
announced in his blog
a Binary Arithmetic package. Here is my version of it.
I'm trying to trap the exception generated when the member operator (:-) is used with a variable that is not a module. I thought the following would work:
catch "`NotAModule` does not evaluate to a module":
"`NotAModule` does not evaluate to a module"
Any ideas how to fix this? The generated exception string should match the first catch statement.
I am trying to solve numerically an ordernary differential equation like this
diff(y(x),x) = f(y(x),ya,x) (where ya = y(x=xa), xa a known value)
The trouble is that the initial value y(x=0) is determined by the second equation which is an implicit equation that has no analytical solution (no explicit expression), and it also depends on the solution at x=xa.
Kindly let me know how to write the code to solve it!
Here is the simplest program for obtaining the set of prime numbers less than or equal to
It is not Eratosthenes Sieve though. The program ES below implements the Eratosthenes Sieve,
Please, i need the code for an implementation of Eratosthenes Sieve, i need a program that calculate primes less or equal than "n", thanks and sorry for my english(i'm from Spain).
How do I round to a certain number of digits after the decimal point?
Is there an easier way than the one shown below?
How do I format a set of strings consisting of numbers and normal text strings. I want to label a color bar like it is shown below. Each last digit of a number should be below the last digit of the number in the string above.
Is used the following command to create the label of the color bar:
P.S.: What is the maximum file size of an attachment to a post? I couldn't attach an image that's 8kb big.
