MaplePrimes Questions

The MapleSoft site mentions Maple 11 for professionals, Maple 11 for Academia and Maple 11 for students. What is the difference between the three? Thanks in advance !!
How do I solve an equation such as this: z(t+1)=1+a*b-((a*b)/z(t)) Finite time of T periods so there is a boundary condition of z(T+1)=0. Need to solve backwards for z(t).
Hello, on one of my procedures, i have the following error message "Error, first argument to _Inert_ASSIGN must be assignable" And I absolutely don't know what _Inert_ASSIGN refers to... May somebody help me ? Thank you.
I've got the following inequality with `in`(z, complex): 3*Im(z)^2-1
I have Maple 10 and it doesn't want to solve it for me. Furthermore how could I plot the area of this inequality in gaussian complex number plane?
I hope you can help me. plumbum
hi all if i have random points in xy plane and for each point i have few measured values how can i fit a surface through that points?
Hi, I have the following equation which I want to plot V against t for t=0..10 and V=0..3000. V=1.186*10^3*exp(-9.478*10^(-3)*V)+749.579*0.455*exp(-t/0.245)+0.0375*exp(1/(4*t+1.2)); Ive tried to solve numerically and came with the following: V=105.5074910 LambertW(11.24090800 (e)^((-3.232551942 (e)^((-4.081632653 t))-0.0003554250000 (e)^(((2.500000000)/(10. t+3.))))))+341.0584450 (e)^((-4.081632653 t))+0.03750000000 (e)^(((2.500000000)/(10. t+3.)))]] Im not sure how or if this can be done in Maple.Any help would be very appreciated Regards, Nasos
Hi, I have the following question: Is there in Maple (v 10) something like the Matlab "find" command, which, in short, returns a position of a vector (or array, etc.) entry satisfying a given condition?? Thx
Hi, I am writing my output using printf(...) procedure. Sometimes I would like to use bold font. Is it possible to interfere with maple 10, like this kernelopts(.... turn bold on :-) .....) printf("something in bold\n"); kernelopts(.... turn bold off :-) ....) printf("something not in bold\n"); Is any way to do this?
Hi, Sorry if a question like this has already been answered, but I didn't find any similar ones. I have a matrix that may look like this: M:=Matrix([[1,[0,0,0],[0,0,0]],[lambda,[0,0,0],[1,1,0]],[lambda,[1,1,0],[0,0,0]],[lambda^2 ,[1,1,0],[1,1,0]]]); only much larger... maybe with RowDimension 200000. Is it possible to use LinearAlgebra:-Map involving some conditioning on different rows. Say "Map the first element of each row to zero if the second and third elements are equal". I can do operation in different columns like: Map[(i,j)->evalb(j=3)](x->2*x,M)
I am trying to export a command from Maple 10 into, say, Word. I noticed that when the command exceeds a certain length (??) then it's being put into two lines. whereas the original was just one. I am using cut and paste special. It happens regardless of what format you use for paste special. ditto concerning the paragraph format in word. any help appreciated. thanks
Using with(Units) If I enter something like: P := 1 [[atm]] And then right click to convert this to torr, it does so like this: P := 1 [[atm]] -> 760 [[torr]] But then, if I check the value of P, it is still given in [[atm]]. How can I make the new units append to the previous value? In general, I'm having a difficult time working with units in Maple. Any suggestions?

Suppose I have the following in my worksheet > a:=17 > expr1 := a^2 +4: > expr1 293 > a:= 0: > expr1 293 Its clear what's happening - expr1 was defined when a was 17 and it doesn't change just because later I change the value of a. I understand that after I set a equal to 0, if I had moved the cursor up to the line where expr1 was defined and pressed the ! button the value of expr1 would change to reflect the new value of a. My question is, is there any function in MAPLE such as redefine(expr1) which will in effect move the cursor to the line on which expr1 was defined, press !, and then move the cursor back to wherever it was?
Hi there, I've just started using Maple, and must say it is a real good tool - powerfull!!! But to the point, I have created a 'simple' procedure for determinig the shape of UMP Unbiased test for testing H0: the probability 'p' of getting "1" in the Bernoulli scheme is
I, i need to plot a z-trasformed function (discrete function), that has some "Dirac" (isn't a real Dirac function) points. How I have to do? This is an example: f:=1/2*(charfcn[2])(k)-3/4*(charfcn[1])(k)-3/8*(charfcn[0])(k)+3/8*2^k;
