Here is a recent session on Maple 12.1. The exact thing happens on Maple 11.5. I define a vector x , Maple acknowledges the fact but then if I ask if x is, in fact, that vector it says no. Any idea of what is going on? with(LinearAlgebra): > x := Vector(2, [1, 0]); Note Maple correctly prints transpose [1 0] on screen. [1] x := [ ] [0] if x=Vector(2, [1, 0]) then 7 else 3 end if; 3 is(x=Vector(2, [1, 0]));

Hi,

I'm trying to solve a system of equations in a matrix. The matrix is of the form <(1/5)*sqrt(6)*c[3, 1]+(1/7)*sqrt(6)*c[3, 3],0,(2/7)*c[3, 3]*c[3, 1]+(2/9)*c[3, 3]^2>, which I want to equate to <0,0,1> to simultaneously find numerical values for c[3,1] and c[3,3]. I then need to take these values and imput them into a bigger matrix and repeat; I think I can do that but I'm caught up on this part. I've tried various commands from linalg, LinearAlgebra and Student[LinearAlgebra], with very little success.

Any help would be very much appreciated.

Hi, i have a rather basic question. Both code pieces do the same:

restart:
 for i from 1 to 5 do  a[i]:=i;  end do;

a[3];

3

restart:
 for i from 1 to 5 do  a(i):=i;  end do;

a(3);

3

 

In which case should  i use round brackets and when square brackets for indexing ?

Does it matter ?

Hello

I have this problem:

I have two non linear equations with twos solutions (Ea and F in the picture)

I need the alpha that gives me the max Ea

How can I enter this in maple.

Thanks a lot!

I attach an image of the equations to be more specifyc

HI,

Does anybody know about this function, that is no more in Maple as a spécial function?  I search the web and I can't find the series that represent this function.  Is there somewhere a Maple's user who have program it so I can use it in Maple 12?

If I do   5466!   I get a number with a bracket saying 17859 digits.  Okay so now I want to explore that number ....

When I right click and explore.  A little explore window pops up an that's it.  No exploration of the number what-so-ever.  How do I explore that number?

Hi all,

when using solve to solve a simultaneous equation e.g. " solve({6*c+d=24,6*c^2+d^2=96}; " I will obtain two solutions, or with different values maybe even more, I want to put the solutions into an equation e.g." c^6*d" and obtain the maximum value from all the sets of solutions I have.

Any help I will be very grateful, at the moment I am working out by copying and pasting but it will get much harder as the number of solutions increases.

Thanks,

Alex

hi everybody

View file detailsI am trying to create a point plot from a data file, with the first two columns, x,y, and the third column as the error in y.

I can make the pointplot with the first two columns, but trying to add in the third colum for the Errorplot in statistics program is not working.  Is there a way I can use this third column of my data file to be the yerrors= part of Errorplot command?

Hi everybody,

I'm using Maple 9.5 on a mandriva station to do some analysis for my PhD. In the end, I get a plot with 2 curves : one is continuous, and the other isn't (it's a kind of Heaviside).

I didn't find a way to do a proper plot, including greek symbols, and formulas in the legends with maple... For this reason, I decided to export the results from my plot to a file containing on each line couples (x, y) and then plot it properly with another tool (gnuplot...).

Given two functions (y=x^2+8 and y=x-6) how can I find the shortest distance between the two? And how do I find the points on these functions that are the least distance to the other? My teacher hinted that parameterizing the curves would help, but I still have no idea what to do...

How can I get random drawings from a list with data in the range of mean + - 1 standard deviation?

I know how to do it for a theoretical normal distribution

with(Statistics);
S := Sample(RandomVariable(Normal(0, 1)), 1000)

but not for an empirical distribution....

Hi, I need to construct a heap using a list. Have found this in Maple help. > h := (heap[new])(lexorder, greg, tony, bruno, michael); (heap[insert])(stefan, h); stefan > (heap[size])(h); 5 > (heap[max])(h); tony > while `not`((heap[empty])(h)) do (heap[extract])(h) end do; tony stefan michael greg bruno

I encounter a situation demonstrated in the following piece of codes:

I'm playing around with the embedded components, mostly buttons, sliders, labels, and plots.

Is it possible to include special characters such as omega or pi or beta on the label, or as the text on a button, or in the legend name of a plot? If so, how?
