Hello,

it's my first utilisation of MAPLE, and I want to determine the max of a function y(x). I have this differentiel equation with 2 variables :

a*diff(y(x),x,x) + b*(diff(y(x),x)-diff(z(x),x)) + c*diff(y(x),x) + d*y(x) + e*(y(x)-z(x))= 0;

I resolve it whith the function "dsolve", and now and I want to calculat the max of the function y(x).

can any body help me ??!!!

thanks

I worked a problem in my textbook using maple.I define two differential equations sys1:=[dy/dt=...,dx/dt=...] and its linearize point lin_point:=[...],then using linearize command,I obtained a state space description of the system.Now,I want to using state space description to get transfer function of the system,how can I do it directly without retype the state matrices a,b,c,and d manually?

Thank you!

Hi,

I have downloaded the lead acid battery model from the link http://www.maplesoft.com/applications/view.aspx?SID=34125. I have made the whole system as a subsystem block and tried to generate a simulink sfunction block, but I was not successful. I am getting the below error while doing so.

Jacques' post on the maple.vim project spurred this post. Vim users cannot have all the fun.

About a year ago I wrote an Emacs front-end for the Maple debugger. I've used it since---it is now my primary debugging tool for Maple code. What it does is allow stepping through interpreted Maple code in an Emacs buffer. That is, rather than being presented with a single line of...

I am trying to create a Simulink component block from a MapleSim subsystem. I have one input to the subsystem, and the Specified Inputs and Outputs section of the MapleSim Connector worksheet also shows that the subsystem has one input. However, When I export the model to Simulink, there is no input port, just one output. How can I fix this?

Sorry but my question os more for mathematica users: The DSolve result is not correct. What can I do?

Thanks for your advice.

Hi Maple users,

I have a license for the Global Optimization Toolbox (GOT) 12 (i.e. for Maple 12). However, it seems it cannot be installed under Maple 13. As the GOT is essentially a frontend for an external library, I find this restriction a bit artificial and annoying. I don't see a reason why I should buy a new license for something that is practically the same that I already bought...!? Do I overlook something? Is there a simple way of installing the GOT 12 under Maple 13? Thanks for any hint!

So I followed the exact example as in the Maple help for "Matlab[evalM]" which is reproduced below (with my result, which is nearly identical to that in the help example)

Hi All,

I cannot transfer variables from Matlab to Maple as shown in the demonstration video for Maple toolbox for Matlab.

Here is what I did:

I run the Matlab using: matlab-sym-maple.bat and checked that it is using the maple (not the symbolic toolbox version): toolbox_version maple

open my maple 13, do version() got: User Interface, Kernel, Library, Maple Toolbox for MATLAB: 397624 back in Matlab: >> syms x y >> g=int('sin(x*y)^2*x',x) >> setmaple('G',g)

I'm new with maple and I can't seem to fix my problem. I want to enter in a textbox1.text in Visual Basic, a function -cos(x) for example- and calling a maple procedure to differentiate it and print it in textbox2.text

I've tried EvalMapleStatement and tried also to convert from maple object the result of diff() function with MapleToString.

Maybe you can also tell me what sort of result returns the function diff(). VB recieves only some numbers that are different for every function I input in textbox1.text from what i've done here.
