Hi.. Is there a Maple pcocedure to evaluate the arithmetic mean of the n preceeding datas (of a data) in a list of numbers? Thanks
I just wnt to know that in maple programing if i have a set of system of equations in which subscripted variables are used then how we find the solution of that system for example we have set of equations as eq_set:={-v2,1-a2=0 ,3v0,3+2v2,1=0 , -b2+3v3,0-2v1,2=0 , v1,2=0} here we want to find the values of subscripted variables v2,1 ,v0,3 v3,0 , v1,2.Kindly help me.
Hello, In C one can use the preprocessor to #define a string literal to be inserted elsewhere in the code. Is there a way to do something like this in Maple? I ask because I am defining a BVP that includes another function as part of the derivitive, and dsolve rejects this, saying that it can't handle a BVP differential algebraic equation (I dont know why it can't do it!). Inserting the expression in place of the reference to the function gives no problem. Thanks
Hello, I'd like to use the BVP solver to find the numeric solution to a large set of differential equations. The thing is, I have about 60 equations differing only by constants in the derivitave. Instead of typing in a set 60 equations with different constants, is there an easy way I can create an array of equations and use it with dsolve? Thanks!
I've got a promblem now. My teacher wants me to write a normalized programme with maple, yet I do not know how. I would like to know where can I find a normalized programme with standard format. If anyone who are familar with this subject, I am glad to accept your suggestions. Thanks very much:)
I could use a hand with a problem our class has. we have the function xy+yz+zx=3 I would like to find a way to graph the surface, the tangent plane at the point (1,1,1) and the normal line all on the same graph. We have tried a couple different methods and have failed miserably. We are using Maple 10 Thanks in advance! Michael
Hi How do I plot and solve Gabriel's Horn in maple. I will really appreciate your help. Take care
How do I integrate a purely numerical function, say f = evalhf @ sin,
and using the NAG routines only ?
In linear algebra multiplication of a scalar and a matrix can change order: aM=Ma, where a is a scalar and M is a r by c matrix. In case of four matrices K,L,M,N the product KLMN is the same as LMNK if the product LMN is a scalar. However, Maple does not allow the forementioned change of order, because the program only checks whether adjacent matrices are conformable. How can this change of order be done in Maple? The issue is that I want to check my work using Maple. TIA Harry ps. is there a brief notation in Maple for scalar by matrix multiplication?
I would like to know how do I find the area under a curve. The curve is 2 D and the data to plot the curve is available. Thanks you

I have only one question, how could I plot the following function correctly?

> f:=x->piecewise(x<-1,1,x=0,2,1);

f := x -> piecewise(x < -1,1,x = 0,2,1)

I try this command but I do not reach the correct result.

> plot(f,-3..3, style=point,discont=true,numpoints=100);

hello! i have a problem that drives me crazy the last days. i'm a switcher from windows to mac and i can't live without maple. but when i want to superscript for example x^2 in maple it shows me x ^ 2, so i can't solve a function that easily, because the superscript isn't accepted. but when i copy the caret out of an predesigned example it works fine. do you can tell me how i have to set my preferences that it works as easy as it does on windows? i hope you understand my problem and i hope that you can excuse my bad english! with kind regards, max pfister

This is a quick programming exercise to correct the following problem in Maple:

for n from 8 to 12 do 
  A := Matrix(2^n, 2^n, storage='sparse'):  # zero matrix
  print( 2^n, time(LinearAlgebra:-Transpose(A)) );
end do:

The problem is that the LinearAlgebra:-Transpose command is not sparse. That is, the time it takes is proportional to the overall size of the matrix and not to the number of non-zero entries - even when your matrix uses sparse storage. In this post we will look at what is required to program a new Transpose command which can handle much larger matrices.

I need to find the trace of a matrix A. What is the command for that? I can't find it in maple's help. (I'm using Maple10 if that changes the answer) Thank you!
