dear i have very complex problem may it wil easy for somone, i have 36 equations in maple that i have to use in matlab to simulate and the equations have to take som numercal values in matlab, and it has to generate some numerical values while running in a loop. i have used the with code generation option in maple. and it produce a code for matlab.
given a n*n Square Matrix (n is known), what is the easiest way to calculate all minors of this matrix ? There is a minor command in LinearAlgebra, but it seems to refer only to the first minor, that are the determinants of the reduced (n-1)*(n-1) Matrix. But I want the minors of a given size, specified by me. An application would be a test of definitness (Sylvester's Criterion). Using Maple13
Would anyone help on how to assign equations in a list to an index variables in a list. Below is my equations.
Eq := [seq(A[i], i=3..n)] = [seq(M[i -1]*a/(6*E*Ipile) + 2*M[i]*a / (3*E*Ipile) + M[i + 1]*a / (6*E*Ipile) - (Delta[i - 1] - Delta[i]) / a - Delta[i] - Delta[i + 1] / a ) = 0 ), i=3..n)]
When I tried the above, I was expecting Maple to assign A to the first equation in the list on the right hand side and so on, but instead I was getting an error message.
<p>I'd like to visualize my daily work and plot a curvature flow. First of all, I need to define and to plot a hypersuface. How do I do that?</p>
<p>Afterwards I'm going to calculate it's fundamental form and other geometric quantities.</p>
Dear Sir / Madam,
Attached is copy of worksheet developed in MathCAD that I would like to develop in Maple. I have copy and paste what I developed in MathCAD into a Maple worksheet to see if any body can guide me. I have posted previously an excel file with Canadian steel sections on Mapleprimes. My goal is to be able to auto select a steel section from the database into Maple for computation.
Please, would anyone guide me as to how to develop the attached worksheet into a Maple worksheet.
find volume of the solid obtained by rotating the region bounded by the curves y=0, y=sinx, 0<=x<=pi about line y=-2.
I got as far as the diagram and the starting off equation.
If I could get some help that would be great. Thanks
I have a differential equation
diff(N(t), t) = r*N(t)*(1-N(t)/K) - p(N(t)), N(0) = N0
p(x):=piecewise(0, x<0, S/(N_crit)*x, 0<= x<N_crit, S)
This equation represents the population growth model where the predator is present.
I need to solve a 2 order hyperbolic PDE (The Wheeler-DeWitt equation for a closed universe), numerically, with some sort of complex initial/boundary conditions. It seems that the program is executed and the module is returned, but while I use the plot, plot3d, value… commands for different values of time variable (\phi), the following error is appeared on my Maple 12 worksheet:
Call me stupid but I still wasn't able to run the simple example in the maple help (see http://www.maplesoft.com/support/help/view.aspx?path=Define_external ) regarding calling external, precompiled Code (in my Case: c++).
Seems simple enough but I can't find how to select the whole part of a decimal number. I want to use the number with mod.
I'm not sure if this can be done in a current worksheet but I'm pretty sure it has to be done in a separate worksheet.
What I'm trying to do is set up a running loop that automatically displays the amount of time the maple kernel has been in use, say every 600 seconds or so. I know I need to use time[real] but I need it continuously running if I want it to display times, right? Which means I need it to run in a separate worksheet I think.
Any ways that I can do this with maple?
Hello have a text file full of x,y,and z Coordinates. Im trying to create a Topographical Map using these coordinates. How can I use Maple to plot these points and show me the contours. Prefereably I would like to have a 3D model of what im ploting
Thanks for any help or advice
can any one help how to plot streamlines for any given velocity vector field. or any one know strean proc please.
