I am converting a complex worksheet from linalg to LinearAlgebra, and
discovered what is to me a serious problem. With linalg, one could use
the basis(A,colspace) command to give a basis of the column space consisting of columns from the original matrix, guaranteed to be in the order in which they appear in the matrix. This is useful in extending a spanning set of a vector space to a basis of a larger space, and allows one to determine exactly which new vectors need to be added. However, the ColumnSpace(A) command in LinearAlgebra does something quite different. It gives a basis of the column space which does not preserve this order, and does not even use the original vectors.

I have two matrices, and I want Maple to test and see whether they are different to each other (as part of a for to while loop -i.e. it will keep looping until the matrices are the same). However, even when they are identical, it returns a value of true to evalb(A <> B). What can I do?

When I try to run this particular programme, it pops up and tells me "Clarify Expression" - "Parts of the expression are ambiguous. Please select one of the suggested meanings." However, before the suggested meanings it quotes the line of programming that this happened on. When I made the programme, I did it line by line, so I know what the suggested options are, and which one I want. However, now the line of programming is such a big block of text that the window goes completely off screen. There's no way to resize it, and I can't move it high enough to see the options. What can I do?

I have installed Maple 10 Build 190196 and I wish to retain the settings and preferencess of Maple 9.51 Build 963582. Which files should I retain from Maple 9.51 before I uninstall it? Where should I place them to retain the 9.5 settings in 10? Thanks, Bill

I have the fuction F/sqrt(m^2*(omega^2-omega_0^2)^2+b^2*omega^2 and i need to fit data to it using the LSSolve command, i have no idea how to do this any help would be much appriciated. thanks.

I would like to hyperlink or insert acces to other program files. I can do this in MS Work and Scientific Notebook. Ex. I can execute Vpython simulations, audio files, saved web pages, etc. Thanks

Hi, can you advise how I can draw geometry objects like circle, triangles, polygons, angles in triangles, etc accurately -- I need the gepmetric shapes to be to-scale -- in other words, if I need an angle at 50-degrees, I don't wish to eye-ball it, but I really need it to be 50-degrees. Thanks!

Hello, i'm a father and my son is at school, he asked me if I could give him some help on his maple project. He has to write a pascals triangle using List, is there anyone who can help.Thanks, Ronald.

Hi, I would like to find the critical points of a formula like: f(x,y)= 5e^((-x^3)-xy/3-y^2/3)cos x cos y But I don't know how to do it, can someone help me? regards, Patrick

Hello Memebrs,
I want to write a code in Matlab, that will find a best fit. I have 4 columns of values. The Red, Green and blue values and in the fourth column the temperature values. I want matlab to intelligently find me the best corelation between the RGB values and Temperature. Any pointers as to how i can go about doing this. Ofcourse the main goal is to get the best fit with minimum error.
Thanks in advance..

This problem agonize me for a long timeand i cant to solve it.
For example, in one TextField in maplet i want to insert e.g. "0"
and in second TextBox to get result of e.g. cos(0) apropos "1".
But i get cos(0). I was try to solve this with eval, evaln and evalf command but nothing get.
Won't to insert number in one TextField and to calculate e.g. cos()
in other TextBox. Someone know how to?
program:
restart;
Calc:= proc()
global theta:
cos(theta);
end proc:
with(Maplets[Elements]):
DKP:= Maplet(onstartup = A0,
Window[W1](title="DKP", [TextField[theta](),TextField[result](),

How can I create a menu with Maplet Builder?

I need to plot the taylor polynomials of sin(x) up to degree 7, i know the functions and i inserted this command: plot({f-g+h, f, f-g+h-i, f-g, sin(x)}, x = -Pi .. Pi, y = -2 .. 2, title = "Taylor Polynomials of Sin(x)") where f g h and i are simple taylor polynomials. Now my question is i need to label the graphs, i tried using legend="..." but i get the error: Error, (in plot) the legend option cannot be used when ploting a set of objects so how would i do this? any help is appreciated

Hi. Many thanks for your time. I'm just trying to get some help on getting maple to calculate the values in an algorithm. Can you suggest where I can access some help pages? The algorithm consists of 3 interacting elements; alpha(i), gamma(i) and epsi(i). The object is to compute the first however many (say 1000) iterations of epsi(i). To do this you need the first however many iterations of alpha(i) and gamma(i). Each value 'p' represents a different algorithm. (ie. a different set of the algorithms alpha (i), gamma (i), epsi (i). I put the *** around the information which is redundant for my purposes but which may be useful in terms of programming.

Hello, I am trying to animate a solution to a set of coupled second order differential equations but I am getting what looks like the concatenation of the velocity with the graph I am plotting (note the bump to the left of the solitary wave). I am also looking to make it a bit more precise so I do not see all the distortion as the animation runs, I believe this my be due to the approximation of the numeric solution. Any help would be greatly appreciated.
Sincerely,
M. Hamilton
