Hello guys, I'm a new user of Maple and I'd love some help.

I'm trying to solve a cubic equation with four variables, and plot the imaginary part of 'w' as a function of 'x' for different values of 'y' and 'z'. When I ask for all the equation roots, the result is huge.

I want to know if there's an "easier" way to select each root of the equation and make it a function without having to "select element" and copy/paste, because I've tried this way and it's not working.

I know this is a stupid question, but I could really use some help.

Thanks for your time!


I am trying to solve a linear system involving large number of equations with constant coefficients using Solve command from the LinearAlgebra package. The maple program is giving solutions for a smaller number of equations (T=10,Ne=20,Ng=15). But if I increase the number of equations to (T=20,Ne=30, Ng=25), then I got the error kernel connection has been lost. I need to increase the number of equations beyond this also. Any help to simplify the code or finding errors is appreciated.

can maple do a real time update graph by for loop read file data?

i can only think that use for loop and read file and draw a sequence of graph,

but memory will be accumulated to consume

just want to make a dashboard to display a multiple of graphs

would like to point to graph then it highlight graph with virtical line

and mark 1 in one of row in one of column in table like data 

just like define feature manually for machine learning but using graph






no matter what e is , expect to output the same 0.733333


chosen1 := [[1,2],[1,20],[3,4]]:
chosen2 := [[2,3],[20,3],[3,4]]:
chosen3 := [[3,4],[5,7]]:
chosen4 := [[4,5],[5,6]]:
chosen5 := [[5,6],[7,9]]:
hashtable can not work 
for example
[1,2]'s 2 as key to find 3 in chosen2 [2,3] then use 3 to find 4 in [3,4] then use 4 to find 5 in [4,5]

[[1,2],[5,7]]intersect [[1,2]]

return [1,2]

there is error when run this.

search start from a, b, c, ... for each sequence if input a,b,c,d,e,f,g,h,i,j,k

is there a function like accumulate in haskell in maple instead of using for loop?

would like to search something if found, then return the length of it searched from the starting position

when start from a search a from b to g whether is a,  if find , return the length from c to the found position,

when start from b search b from c to h whether is b,  if find , return the length from c to the found position


then save the length into a list

a b c d e f g

   b c d e f g h

      c d e f g h i

         d e f g h i j

            ef g h i j k


How do people test BIBD design in maple?

what are the different when using different field when test design ?

how to design a game that is suitable for the specified field of the design?




array out of range 

according to book, is this calculation?

how to calculate like the book do?


i use function

but not work

A list must have only 7 one and 50 zeros

length of list is fixed and equal 57

how to list all combination above?

How to generate any possible points projective plane for sets of numbers?

bonus is any possible field

I have an equation

2*x + 3*x^3

would like to change to

x1 + x2 + x3*x4*x5 + x6*x7*x8 + x9*x10*x11

Even and odd complement each other

how to find other sequence which complement each other?

such as 3 sequences divided integers or 5 sequences divided whole integers

is there monomials creation method such that solve result about coefficient and power are integers when right side columns are sequences?


i find even multiplication numbers are always solved into integers coefficient and power.

is there any more other sequences?

if I choose six multiplication table sequence, 

what is this complement of six multiplication table sequence?
