In one case, I have a sequence that starts at zero and increments by 0.1. I enclose it in square brackets to form a list.  I have another list of function values evaluated at these points.  Then, I have a similar sequence that starts at zero, but increments by 0.05.  Again, I evaluate the same function for a total of 4 lists.  Two inputs, two outputs. 

I create a table from these and want to get the data out at, say, 0.2. 

Hi, all When I read the contents read from a file, I found the order was different from that in file. For example, In file a.txt: a+b+c; d+f+g; b+c+d; d+e+g; m+g+a; a+m+f+1; After reading, I stored them in a list: L := [d+f+g, b+c+d, d+e+g, a+m+f+1, m+g+a, a+b+c]; The order is changed somehow. The procedure I am using here is: HandleGB :=proc(file) local line, T,L,f,cnt; f:=fopen(file,READ); try T:=table(); line:=readline(f); T[cnt]:=parse(line); for cnt do line:=readline(f); if line=0 then break; end if; T[cnt]:=parse(line); end do; finally

How can i delay the evaluation in add. I want add to return

add( i, i=1..10)

                                    1+2+3+4+5+6+7+8+9+10

Now it returns

add(i, i=1..10)

Hi everyone!

Based on a recent post ( www.mapleprimes.com/forum/partialsubstitutionfrontendfreeze ) I have the following piece from a Maple worksheet, which I do not understand. First, I define A and B, where A is supposed to be substituted into B. If I have a "p" in A, then I get a "subs" as variable in B after frontend/curry with subs:

I am trying to set a timelimit for each loop, i.e.

for i from 1 to 10 do
    try
        timelimit(10,print(someproc())); #print result from the procedure being called
    catch "time expired":
        print(i, "time expire");
    end try;
end do;

However, it doesn't move to the next loop. It just terminates after completely the first loop (i.e. i=1).

If I am correct is the gradient of a the 3X3 tensor each element on the same row differentiated with each coordinate variable x, y ,z or is that a different operation?  I am unable to find the correct operation or I am not using the MAPLE command correctly to get an output.  I did load the Vector Calculus package.

What is my problem??

hey do u know a website where i can find information about gravel pacing and screen of a bore hole..i really can't find anything

Dear Community

I have a problem with units definition,I'm working with maple with kgf and tonf,

I read in help page this "A tonforce is defined  as the force of gravity on a short ton.......", so when I convert 1 tonf to kgf I get 907.18kgf,

I know this is OK, but since I don't use short ton in my country I would like to define in METRIC 1tonf = 1000kgf.

How can I do this? Here is a conversion table where it says 1tonf = 1000kgf (metric), not (short)

Hello,

I  would like to perform inverse Fourier transformation, but I get an error message::

restart;Fs:=75e6;Ts:=1/Fs;:g:=add(Dirac(t-k*Ts-6*Ts),k=1..4);G:=inttrans[fourier](g,t,w);
 

Error, (in gcd/gcdchrem1) input polynomials have too large a degree
 

I have Maple 13.

Thanks four your help in advance.

 

Hi, To see the body of a procedure in Optimization[Interactive] module, i use this method: interface(verboseproc = 2); kernelopts(opaquemodules = false); print(Optimization[Interactive][BC]); but "too many levels of recursion" Error occurs! Note that this method works for other procedures in this module, for example test it for Optimization[Interactive][InittoText]. What is problem for "BC"? and what is the solution? thanks.

Hello, I have an equation with 200 variables and I want to assign them to a 1 column by 200 rows matrix. My variables are named ΔX_i where i goes from 0 to 100. My Matrix is named Matrix.

I have tried something like that:

ΔX_i := Matrix(i) but I get "Error, unsupported type of index, i"

Any ideas?

Thank you
 

My teaching has maple 12 in class and provides files online of his lectures.  I tried opening the file using maple13 at home and when it opened it was a bunch of junk.  Is there a way to open older versions of maple on maple 13?

 

Thanks for the help,

please help me here

we want a "remember table assignment for the first derivative evaluated at a point a1" for example

D(f)(a1):=0

but using this command maple creates a proc

for example using the command

f(a1):=0:

maple asks : 1. function def. 2. remember table assignment

but using D(f)(a1) :=0 just creates a function def.

Very likely there is a very simple solution to this question, but I searched Maple's help pages and this forum and didn't find a solution.  Probably because I don't use the correct English terms.

given two functions

(1) X := x->f1(t);

(2) Y := y->f2((t);

witth t = -infinity...infinity; f1 and f2 arbitrary functions of a parameter t

How I can get the function

Y := x->f3(x);
