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.
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:
> 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')],
> [Button("OK", Evaluate(function='setdata()'))]
The Commented out "Table" line fails and the "TextBox" works OK. Is there a way to have this data appear in Table form?
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)?
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...

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.
Is it possible to change and save the default background color and pen settings for a sketch?
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
Hi guys ;)
I have a question. Is it possible to apply a PID controller with the following parameters(P=6,I=4,D=0.02)to a Non Linear System described with the differentiate
equation like this
or in the second form, as two differentiate equations like
dx1 := (x1,x2) ->x2;
dx2 := (x1,x2) ->((u*ki)^2*kc)/(mk*(x1-x10)^2)-g*mk/mk-kfv*x2/mk;
without linearisation in operating point, where u - is input variable, x - position,
dx/dt - velocity, d^2x/dt - acceleration ?
Thanks for your help.
I need to generate pimitive polynomials of degree 17 over GF(2^32) for use in an LFSR working over 32-bit words.
Does anyone know how it can be done?
I try to deduce distribution fonction from a parametrized set of points with Maple.
At this stage I have a dataset define through a relationship like y=f(x), and I want to obtain the distribution of y points, given that x in [-A,A]. The theoretic formula is : F[Y](z) = P(y<z).
i.e. F[Y](z) = Int(delta[f(x)< z],x=-A..A);
and I use the piecewise Maple function to implement it ( Int(piecewise(f(x)< z,1,0),x=-A..A) ), but for Maple :
Int(piecewise(f(x)< z,1,0),x=-A..A) = piecewise(Int(f(x)< z, x=-A..A),1,0))
which is totally different !
If I have f:=x^2+1000*y: and under contraint g:=1000-x-y: how Do i find this Min or max with the hessian Bordered style ..... I allready know how to do the Lagrange version but this hessien ... im out .. and if it's the same ( because it's gona give me the same answer as if I do it with the !!!!!! Student:-MultivariateCalculus:-LagrangeMultipliers(f,[g],[x,y]); !!!! ) Thanks very urgent ! ( Im using Maple 9,5 if that makes a diff) Tx Jp
