I want to call a procedure or function by clicking a button. How to call a procedure from Maplet Builder: Evaluate -> function? And where I have to write this procedure: to save it - in Maple 10 worksheet like file *.m in the same folder where file *.maplet is?

I am converting a complex worksheet from linalg to LinearAlgebra, and discovered what is to me a serious problem. With linalg, one could use the basis(A,colspace) command to give a basis of the column space consisting of columns from the original matrix, guaranteed to be in the order in which they appear in the matrix. This is useful in extending a spanning set of a vector space to a basis of a larger space, and allows one to determine exactly which new vectors need to be added. However, the ColumnSpace(A) command in LinearAlgebra does something quite different. It gives a basis of the column space which does not preserve this order, and does not even use the original vectors.

When I try to run this particular programme, it pops up and tells me "Clarify Expression" - "Parts of the expression are ambiguous. Please select one of the suggested meanings." However, before the suggested meanings it quotes the line of programming that this happened on. When I made the programme, I did it line by line, so I know what the suggested options are, and which one I want. However, now the line of programming is such a big block of text that the window goes completely off screen. There's no way to resize it, and I can't move it high enough to see the options. What can I do?

I have installed Maple 10 Build 190196 and I wish to retain the settings and preferencess of Maple 9.51 Build 963582. Which files should I retain from Maple 9.51 before I uninstall it? Where should I place them to retain the 9.5 settings in 10? Thanks, Bill

I have the fuction F/sqrt(m^2*(omega^2-omega_0^2)^2+b^2*omega^2 and i need to fit data to it using the LSSolve command, i have no idea how to do this any help would be much appriciated. thanks.

How can I create a menu with Maplet Builder?

Hello, I am trying to animate a solution to a set of coupled second order differential equations but I am getting what looks like the concatenation of the velocity with the graph I am plotting (note the bump to the left of the solitary wave). I am also looking to make it a bit more precise so I do not see all the distortion as the animation runs, I believe this my be due to the approximation of the numeric solution. Any help would be greatly appreciated. Sincerely, M. Hamilton

How do i use LSSolve to fit the correct resonance function to a set of experimental data, thanks

I want the data returned from a Maplet Evaluate to appear in a Table. I have listed below an example Maplet: with(Maplets[Elements]): > setdata:=proc() > Maplets[Tools][Set]('expdata'= [[5,42.6],[10., 31.5], [15,28.8],[20., 22.3], [30., 18.7], [45., 14.1], [60., 11.1], [90., 7.7], [120.,4.9], [180., 2.5], [240., 1.3], [300., .7]]); > end proc: > maplet := Maplet([ > # [BoxCell(Table([A, B], 'expdata'), 'as_needed')], > [BoxCell(TextBox['expdata'](3..30))], > [Button("OK", Evaluate(function='setdata()'))] > ]): > Maplets[Display](maplet); The Commented out "Table" line fails and the "TextBox" works OK. Is there a way to have this data appear in Table form?

Hi, I have a matrix containing data read from an external file. I would like the user to select a colon number using a List box and, based on this number, build the resulting vector from the matrix. Is it possible to ask Maple to evaluate some parts (execution groups?) of a worksheet with some command (not menus)? Thanks.

Does anyone here use or has ever used Maple-Connect ? Also how long were you using Maple before first attempting this ?

After reviewing the help pages on the Logic package I noticed that the commands used in examples usually contained an ampersand "&" before them. Does this in any way alter the meaning of the logical operator or (connective) in any from it's usual meaning in standard text ? for example, is &iff "if and only if" ? does ∧ stand for "and" ? does ∨ mean the logically inclusive "or" does &implies mean "if antecedent then consequent" ? and so forth...

Hello members, My question is out of maple primes, but i was wondering if one of the members is and expert in MATLAB coding. I am trying to write a MATLAB code for numerical integration for a double exponential equation of the form i = io(exp(-alpha*t)-exp(-beta*t). The problem i am facing is how to eliminitate the error as the integration is taken as the area under the curve, say from time t=0.0 to t=25e-6. Your comments in how to solve this problem is highly appreciated. Regards, JacquieD.

Is it possible to change and save the default background color and pen settings for a sketch?

HIIIIIIIIIIIIIII! :) I'm doin a problem on the restricted 3 body problem...What i want is to creat a proc "equilibria(mu)" which finds all five equilibria of (DE) when mu_1=mu and displays, in a neat table, the (x,y)-position of each equilibrium and the eigenvalues of the vector field's Jacobian at that equilibrium. In addition, the table should indicate if the equilibrium is hyperbolic (all eigenvalues are real and non-zero), elliptic (all eigenvalues are imaginary and non-zero), hyperbolic-elliptic (a mixture of non-zero real and imaginary eigenvalues), or otherwise.. Now the difficulty is this, i can find the equ's and get the evalues, but i have a proble with gettin them into a table...i've been told that prinf is a good one to use, but i have no idea at which bit to use it..this is how far i've got
