I have been trying to understand the example examples/Optimization LSSolve section (at the bottom) and use it for different data and a different equation, i only want to find residues for omega_o, F, m and b not omega in the equation F/sqrt(m^2*(omega^2-omega_0^2)^2+b^2*omega^2) How do i just find residuals for these four unknowns only. Thanks
i have a program to write and i dont know how to do it. if anybody could hwlp me cheers. Q implement a computer program which fora given positive integer n, a given square matrix A of order n and given vector b which n components, decides whether A is a band matrix with p=2=q and in the positive case solves the system of equations Ax=b by simplification of Gauss Elimination for a band matrices with p=2=q
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.
