This is a personal pet peeve. Let A be a 2x2 matrix with elements 0.5, 0.5, 0.3, 0.7 Find A^2 Repeat with a 2x2 matrix with elements 1/2, 1/2, 3/10, 7/10. Why does the first example give more than 2 decimals? Why is the answer to the first so inaccurate? Is there some library besides LinAlg or LinearAlgebra I should include to handle such rudimentary calcs?

Hi, It´s possible to call a Maple library from a module or a procedure? I try to use the command with, but Maple don´t accept that. Thank´s João Paulo Laudares

In the following qu file for a MapleTA question, if the RESPONSE is

{a<x and x<b} then after the question gets graded as correct, "Your Answer" appears incorrectly as {a<b}.
But if the RESPONSE is

{a< x and x<b} (note there is a blank space after the first inequality sign!) then "Your Answer" appears correctly as RESPONSE.

One could ask students to put the blank space in, but this should not be necessary. Any ideas?

question=Enter this and see what happens.

maple=evalb(($ANSWER)=($RESPONSE));@

Has anyone had any trouble using Equation with structures that are not functions? I am using 2.51, and the following question always returns incorrect. \begin{question}{Equation} \qutext{Test question} \answer{x^2 + y^2 = 1} \end{question} Is there a workaround?

When I use PDEtools in Maple10 to get subscript notation of derivatives it works for equations that are assigned to another variable name. It does not work for equations that are referred to only by their Maple10-generated equation numbers. The sample case below shows the problem. It is an edited Maple-text version. I tried uploading the file, but neither Live Worksheet or HTML copy correctly display. Live Worksheet apparently doesn't access PDEtools, and the HTML copy can't handle equation number references. I can supply the test file to any one who wants it. ------------------------------------------------------------------------------

I know the 'factor' function won't do it. But is there any function available in Maple that will take for example 2*p^2 + 4 as an argument and return 2(p^2 + 2) as a result? i.e. I want to factor integer coefficients. Thanks, Eddie

Hi, I was having a problem to write a Maplet for model selection. My problem is that, the variables from Combobox are not received by the procedure that should make the model selection. I am trying to apply the function parse to transform the string from ComboBox and add it to the variable that will be send to procedure FORMULCAO. Here is the code: > with(Maplets[Elements]): > Cond:=module() > option package; > local maplet; > export Model; > global deptemp,N, NDOM, MODE; > use Maplets[Elements] in > maplet := Maplet([ > [ > "Time Dependence: ", > ComboBox['CoB1']("stationary", sort([

Hello, my problem is the memory!! I have a P4 3.20GHz, with 2.00GB of RAM. I must evaluate a 1296x10000 matrix that consists of complex number that derive from many calculus! Maple software tell me that there isn't enough memory and the kernel connection is lost. How can I solve the problem? Marco

Hello, I would like to define new type in my package but I don't know how. What should I change in followng code to make it work? Thank you. Karel Srot restart: march('create', ".", 3); MyModule := module() option package; export p, `type/FS`; `type/FS`:=proc(t); # define new type if t=`a` then RETURN(true); else RETURN(false); end if; end: p:=proc(S::FS) local coeff, t; print(1); end proc: end module; savelibname := ".": savelib('MyModule'); restart: libname:=libname, `.`: with(MyModule); type(a, FS);

hi I am new to Maple. I have been trying to solve a nonlinear equation, but have been fraught with problem. I would appreciate any help. Solution through 'solve' would be great but 'fsolve' will be ok too. For the solve eq:=int(E^2/(exp((E-Mu)/KT)-1), E=El..EU)) -int(E^2/(exp((E/KT)-1), E=EL..EU))=0) Typical values of E are 10^-19; and KT is about 10^-15.

The MapleSoft site mentions Maple 11 for professionals, Maple 11 for Academia and Maple 11 for students. What is the difference between the three? Thanks in advance !!

How do I solve an equation such as this: z(t+1)=1+a*b-((a*b)/z(t)) Finite time of T periods so there is a boundary condition of z(T+1)=0. Need to solve backwards for z(t).

Hello, on one of my procedures, i have the following error message "Error, first argument to _Inert_ASSIGN must be assignable" And I absolutely don't know what _Inert_ASSIGN refers to... May somebody help me ? Thank you.

Hello,
I've got the following inequality with `in`(z, complex): 3*Im(z)^2-1
I have Maple 10 and it doesn't want to solve it for me. Furthermore how could I plot the area of this inequality in gaussian complex number plane?
I hope you can help me. plumbum

hi all if i have random points in xy plane and for each point i have few measured values how can i fit a surface through that points?
