I have Matlab 2010a(64bit) and Maple 15(think 64bit, not sure). When I setup the matlab toolbox, it installs the 32 bit toolbox with maplemex.mex32 file. When I run the code, matlab searches for maplemex.mex64 bit file. Any idea how I can remedy this? I have Visual C++ 2008 Sp1 compiler setup on matlab. Thanks in advance. ...

so I was wondering if anyone could help explain the following....... In Maple I execute Digits := 100 evalf(5*sin(15*Pi*(1/16))) and it returns 0.9754516100806413392414243423851112046384580887597740387725104474738165939296229011266265461704519090 In Matlab I execute digits(100) pi2=vpa(pi) vpa(sin((pi2*15)/16))*5 and it returns 0.9754516100806413392414243423851112046384580887597740387725104474738165939296229011266265461704519100 hence there is a difference in the last few digits In maple ....519090 In matlab .... 519100 The problem is vpa(pi). A hint, why are the following two lines returns different results? >> digits(100) >> vpa('pi') ans = 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117068 >> vpa(pi) ans = 3.141592653589793115997963468544185161590576171875 "omegayen " <omegayen@ameritech.net> wrote in message news:h571ce$q7c$1@fred.mathworks.com... > so I was wondering if anyone could help explain the following....... > > In Maple I execute > > Digits := 100 > evalf(5*sin(15*Pi*(1/16))) > > and it returns > > 0.9754516100806413392414243423851112046384580887597740387725104474738165939296229011266265461704519090 > > In Matlab I execute > > digits(100) > pi2=vpa(pi) > vpa(sin((pi2*15)/16))*5 > > and it returns > 0.975451610080641339241424342385111204638458088759774038772510447473816593929622901126626546170451910...

greeting all, i'm using nonlcon(nonlinear inequality constraint) with GA from the toolbox provided by matlab. does anyone notice the extreme slowlness in evaluating nonlinear constraint as compared to other linear constraint? my problem for nonlinear constraint is as follow c(1)=x+y^2-2*ones(N,1) where x and y are Nx1 vector. which means if N increases, the size of constraint increases. and to clarify, the min problem is sometime like min c'z where z=[x;y], which means x and y are some range of variable within z(just a matter of problem formulation) well, is there anyone with other alternative or is it possible or method in including non-linear constraint directly to fitness function? (well, actually nonlcon deals nonlinear constraint by using Augmented Lagrangian Pattern Search from what i see from the help file, or am i wrong?) and one more question, is there anyone that attempt to attempt to apply mixed integer problem into the GA in matlab? For now, i can only switch before pure integer or pure real number problem, but not mixed at the moment. I will be trying to add in some repair operator to fix up the variable that needs to be integer and other remaining in real number. I'm not sure why you are using ga to solve your problem. Did you find fmincon unsatisfactory in any way?

I posted a thread over at...... http://www.mathworks.com/matlabcentral/newsreader/view_thread/257642#670417...... regarding differences in digits between Maple and Matlab which still has not been fully addressed.... However, the problem I observe is also seen in just Matlab on it's own.... The behavior has to do with the sym object class. (I am using the Maple toolbox for matlab and Matlab R 2009 A 64 bit) As an example >> digits(30) >> vpa(sym('pi'))*.1 ans = 0.314159265358979342695820259867 >> vpa(sym('pi'))*(.9-.8) ans = 0.314159265358979254731225959353 Both of the above are being multiplied by the same number .1 however the case where (.9-.8) is instead being multiplied yields a different result.....

Hi, I am working on a code in Maple but am having trouble with its size. I was hoping to try to run it in Matlab to see if it would do better. I have only ever used matlab for very simple things and was looking for a little direction on how to translate this. Posted is a small section of what I am trying to do. The vector Mat2 is a filled with number 1 through 10. I want to run a specific if/else routine for each number in Mat2, and fill in a matrix Mat3 as my output, which will be 4708 by 4708. The code runs does the entire array Mat2, and each time it encounters a 3 it creates a row in Mat3 with the values assigned. The output will mostly be zeros with 5 separate diagnols. I tried to translate directly, but keep on getting errors. Any help is appreciated. Thanks > Mat2 := Reshape(Mat, 4708, 1); > t := proc (i, j) if Mat2(i) = 3 then if i = j then -4 elif j = i+1 or j = i-1 or j = i+216 or j = i-216 then 1 else 0 end if else 0 end if end proc; Mat3 := Matrix(4708, t, storage = sparse); ...
