I define the tower function as base^^(-1)=0, base^^0=1, and base^^1=base. In general, base^^(height+1)=base^(base^^height). My program to calculate it has four inputs: base, iter( number of iterations),h(fractional part of height), and k(integral part of height). Two outputs: answer and prec(precision). For example 1.21^^(1/3)=1.1056691794 and 1.21^^(2/3) =1.1702307336. For this program .20<base<1.44, 0<=h<=1, and iter>=20 an even integer. If base<1 or k<=-2 the answer will be complex. This cannot be used for 1.60^^(7/2)=3.0863796925. I would like to put this in my library.

Maple 10 comes in both a 32bit and 64bit version for Linux. It's possible to run both versions, installed to the same base location, on a machine with the appropriate operating system runtime configuration. There are some interesting performance differences between the two versions.

I'll say a few words about the installation. I installed both under /usr/local/maple10 on an Athlon64 3200+ running the x86-64 version of the Fedora Core 2 operating system. I have the 32bit...

Hi all, I'm a new user so...you'll forgive me if I've chosen the wrong forum. That's my problem: I've used Maple 10 3 or 4 times since the installation, but the last time I've tried to start it, the window was completely GRAY; after about a minute an error message appeared saying something about a 'peripheral error' and 'restart the computer to restore the system' (...sorry for bad translation from italian), the interesting thing is that the system has changed its graphical settings about the monitor resolution (800*600) and colors (I think 4 or 16). An other information... I noticed that a txt file was created just in that time and placed into maple directory: 'hs_err_pid1136.txt'; opening it you can read 'An unexpected exception has been detected in native code outside the VM.
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 mk*diff(x(t),t,t)+kfv*diff(x(t),t)-(ki^2*u(t)^2*kc)/(mk*(x(t)-x10)^2)-mk*g=0 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.

Hi. I have a transfer function like this one: y:=(2.5)/((8*s^2+6*s+1)*s); and I can make inverse Laplace transformation in time and plot it by: y1:=invlaplace(y,s,t); plot(y1,t=0..25); I try it also with time delay in transfer function but it doesn`t work. y:=(2.5*exp(-1.5*s))/((8*s^2+6*s+1)*s); > y1:=invlaplace(y,s,t); > plot(y1,t=0..25); So i find a solution in differential equation and make an algorithm to convert transfer function to differential equation. ode := 8*(diff(x(t), t, t))+6*(diff(x(t), t))+x(t) = 2.5*Heaviside(t-1.5); ics := x(0) = 0, (D(x))(0) = 0;
I want to compile the appended code snippet from HelpExamples.c into a DLL using MSVC6 and added C:\Programme\Maple10\extern\include as well as C:\Programme\Maple10\bin.win as pathes to the project. After compiling I get the following error message for linking: Linking... Creating library Release/MapleAPI.lib and object Release/MapleAPI.exp MapleAPI.obj : error LNK2001: unresolved external symbol __imp__ToMapleString@8 It seems that i miss an import library - what should I do (except having a break for some more coffee)?

Hi. I have searched the forums and haven't found any topics relating to what I am experiencing. If there are, I apologize and would appreciate a pointer to where I can get more info. I am creating some course content, and am working in document mode so as to make the document easier to view. I am working with Maple 10 on a mac (OSX 10.4.3). My frustration is this: I get very inconsistent behavior when I try to type a math equation in the document. If I have no typesetting (no sections, etc), then things work fine. If I am inside a section, however, and input something in math mode (option-R on a mac), then when I hit enter, instead of seeing the calculation, it just goes to a new line. Sometimes it gives me a calculation, but not often. I
I'm trying to find the largest prime number in consecutive digits of e but maple seems to have problems with large integers. Does anyone know a way to make this work better? for i from 0 to 100 do a := floor(e*10^i); #e is the natural base e if isprime(a) then print(a); end if end do it finds the first 3, then gives the error: Error, cannot determine if this expression is true or false: isprime(floor(100000000*exp(1))) I believe it is due to precision of integer values.
I would like to know if it is possible, how to plot a function that is stepwise, something like: for x< -1, y=2-x; for -1<= x <= 1, y=x; for x>1, y=2x+1;
Is it possible to do this all on one plot? I'm extremely new to Maple, so I apologize if the answer is quite obvious! Thanks!
can you animate implicitplots? if so, how?
Hello, I need to find a limit function of recurent progression: y0 = a; yn = a + int(x * y(n-1), x) for n=infinity. Thank you very much for any solution P HK
Hi! I have a Maple worksheet comprising of TEXT + MATH, mainly for loops and if statements, using matrices. Can someone please let me know how I can turn this sheet into Fortran code (very detailed instructions necessary!) 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'm trying to solve a partial differential equation with two boundary conditions below.  The general solution contains arbitrary functions of the non-differentiated variable.  These functions are solved for and assigned but do not appear in the final solution return.  Can anybody help me with this?
