How do i show data points on spline on same graph and integrate to find the area under curve. i have the spline and the data but cannot get them on the same graph
How do i use LSSolve to fit the correct resonance function to a set of experimental data, thanks
Hi, I want to make the following integration: R0:=int(-P_m*(-1+exp(-30*Di_d/P_m/(1-u*P_m^v+q*P_m^r)*q*P_m^r))/kappa*exp(-P_m/kappa), P_m=0..infinity) Di_d, u, v, q, r and kappa are all constants, which are all positive parameters. P_m is the only variable (so R0 is a function of P_m). As the solution of the integration Maple gives just the integral sign from 0 to infinity and the unsolved equation. Does this mean that Maple is not able to find the solution? So it is not possible to do the integration? However Maple is able to plot its solution. How is this possible? Is the plotting just an approximation?
Greeings, Can Maple write out the symbolic form of a Taylog Series? Thanks in advance, David
How do i use LSSolve in maple, i have a set of data and a formula and i need to use LSSolve to fit a curve to the data and then plot it. thanks
Hi All you folk with more experience than I have. Question 2. Is there a way to place the legend in a graph next to the graph rather than below it? Question 3. How can I create my own own variable names... I want to place a ˜(tilde) above a character, present task requires the ˜ above a 'v'. Question 1. This was answered unsatisfactorily in "Symbolic characters in plot titles". I have attached a worksheet with my quetsions. Any help will be appreciated :) Thank you Al
Is there an easy way to do numerical differentiation in Maple? I have a set of data, but would like to try differentiating numerically rather than fitting the data to a curve first. Thanks
I have the function f(x,y)=(x^2+3y^2)e^-x^(2)-y^(2), and when I try to graph it with either plot 3d or implicit plot 3d I get nothing. Ant ideas what I need to do? Thanks!
I've compiled and run the samples\openmaple\simple\simple.c from Maple 9.5. How do I get the program to run without displaying the spash screen? When running executables from a command line, this splash screen is annoying. The -q (for quiet) command line arguement does not work. Other command line arguements are evaluated by the api. Give it a non-existant arguement and it gives a usage reply as expected. The openmaple api spawns the spash screen found in bin.win\oms32.exe. Renaming this file causes an error: "Error launching OpenMaple splash screen." I can't delete the file, The error message is just as annoying as the splash screen.
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?
how do i use LSSolve to find least squares solution to a function and plot it. Thanks
Since I accidently changed my system clock to a time in the future and set it back correctly, I get an error when Maple starts. It's an license-error more specific: FlexIm error: -88,309 "System clock has been set back" Maple asks to reactivate, once done that successfully Maple says that after starting Maple again everything will work properly. But it doesn't work, I get once again the same error and the question to reactivate. The error is known by MapleSoft, I got this information: "FLEXlm checks the computer for files with a timestamp beyond the current date. If there are files with a creation date in the future of what the current system clock reads, FLEXlm will return this error. These files must have been created when the clock was set incorrectly. We suggest the user conducts an advanced file search to find the files that are causing the problem."
Hi, I have a function that looks like: f := (x, y, z) -> -(y^x) + z; Now, if x = infinity, y > 1 and z < infinity, the value of the function f should be -infinity. How do I get that result using Maple? I was trying to use commands like simplify, assume and assuming, but I could not make it work. Any help would be appreciated... Thanks!
Hello, all! I have a linear system of real numbers. I copied the example in the tutorial for using LinearSolve and converted my matrix to a float: with(LinearAlgebra); my_solve := proc(A::Matrix) local sz, local_A, B, sol; sz := Dimension(A); local_A := Matrix(A, datatype=float); B := Vector(1...sz[1], 1); sol := LinearSolve(local_A, B); end proc; And when it solved, it got the wrong answer!! It would produce a solution that simply didn't work. When I removed the float conversion step, and just used my original matrix, it worked perfectly. I would love to understand this better... is it because of rounding?
I am having issues creating an array and dividing by the values in the array. Any tips on how to make this a quick and painless process?
