Maple 13 help describes at least two ways to invoke classic maple, one, for example, through the Windows start - all programs -> Maple 13 .  But there sure is no classic Maple option there.  Where is Classic Maple?  ..........Edgar

 

Hello,

suppose I have two (or more) different matrices, not necessarily with the same number of rows but with the same number of columns.

I know I can use RowSpace in the LinearAlgebra package to obtain the RowSpace of one matrix, but I would like to consider the intersection. Is that possible?

(In fact, I am particularly interested in the vectors in that intersection that only take the values zero and one, or in other words: all non-zero entries of which are equal. Would there be a trick for that?)

 

Many thanks!

 

Please help me to Solve the following problem?

3^2^3*3^2^2=?

Hello out there,

Hopefully somebody can help me.

I have a little function lets say: n:= l -> sqrt((C1*l^2)/(l^2-C2^2)+(C3*l^2)/(l^2-C4^2)+(C5*l^2)/(l^2-C6^2)+(C7*l^2)/(l^2-C8^2)+(C9*l^2)/(l^2-C10^2)+1);

(it is a sellmeier equation for the refractive index of quartz

and Maple can also plot it for me:

plot (n(l), l=350...1600)

But now I need the data on which the plot is based to be exported to excel or origin.

I tried the following code...... un := [0, 0, 0, 0]: un[1] := tanh(k)*tanh(k*n): for i from 2 to 6 do uns[i-1] := eval(un[i-1], t = s): und[i-1] := diff(uns[i-1], s): unp[i-1] := eval(uns[i-1], n = n+1): unm[i-1] := eval(uns[i-1], n = n-1): un[i] := un[i-1]-(int((und[i-1]-(1-uns[i-1])^2)(unp[i-1]-unm[i-1]), s = 0 .. t)): end do:

Dear Experts, I am sorry for theis basic questions but I don´t succeed in solving it. I have to matrix A and B with just one column each and 10 values each. So together 20 values. The 10 values of matrix A I want to plot in a graph (the points shoudl be joined to a lign) and the second matrix B also, but I the same graph. Dou you know a solution for that? Thanks a lot!

hello, i just wanted to know how to find the equation of the tangent line for f(x)=x^4-x^3 at the point x=1.2.  what code would be used?  thank you very much in advance.

Dear experts, I have to optimize a function f with two variables x and y --> f(x,y). The function is not differentiable! Does somebody of you know a link where I could find an algorithmen (the best would be a generic algorithmen) to solve this multivariat optimization problem? Thank you a lot in advance!

I want to make my Maple12-procedure faster by creating two threads instead of two:

I have an Nx3 Matrix A and each row looks like [integer,integer,*]. Matrix A acts like a function of two variables in the sense that the ordered pairs that you get be selecting the first two entries of each row are all distinct.

I would like a slick way to convert A to a Matrix B for which B[i,j]=* where * is the third entry in the unique row of A that looks like [i,j,*]. We can insert 0 for "blanks."

For example, if

A:=Matrix([[1,3,a],[1,4,d],[1,1,b],[3,3,c],[3,4,a]]) 

1 3 a
1 4 d
1 1 b

Hi there,

My name is Sasi Bhushan Beera. I am Graduate Student in Mechancal engineering at UB.

I have been working on dynamics of mechanical systems for my research. What I intended to do

was to obtain equations of motion using MapleSim and copy paste them in a seperate document

folder and solve them numerically. Considering the case of a Simple pendulum, I was successful

in doing all this but I had problems with animation of the pendulum.I need some help with the animation

Hi!

Hi all, Is there anyway to solve this differential equation in maple? (diff(x^2, x))*(diff(w(x), x))/x^2 = 480*(Int(0.2538690379e-2*l^2/(exp(4.651162791*10^6*l^2+9.302325581*10^6*w(x)-1.600000000*10^9)+1), l = 0. .. infinity)); Initial conditions: w(0) at 0 and w'(0)=0. Thanks

How do I generate a list of equations with Maple procedure. My problem is this, I have a Pile embedded in the soil. L is the length of the pile, it is divided into t equal segments, thus there are t + 1 points along the length of the pile. The point 0 is at the tip, and point t is at the ground surface. Y[m] is the general deflection equation at any point m along the pile. My goal is to generate each equation for each points along the pile, such that I can invoke Maple solve function to solve the problem. Below is my input into Maple.
