## The Determinant =0, so no solution...

The Determinant to the Equations = 0 so the system cant be solved. Maybe you have an error.

## Break up the Sum...

This Is how I would approach the issue. Could be a problem if l=1 or n.

## Incorrect Variables Listed...

.Replace in solve({.....................},{c__1,c__3,c__4,x}) and it works

## Undefined variables...

You haven't defined "p", you have "ep" so I assumed that to be e*p. You also have defined "del" so I changed that to 1 just to see what would happen. Could be totally wrong but it solves easily then.

## Rank...

Use Rank it is in the LinearAlgebra Package.

Rank(A) returns a value of   5

Hope this helps.

## Compatibly?...

1st. Maple 16.02 is compatible with Win8

2nd Have you tried installing it in Win7 compatibility mode? Would be interesting to know if this works but even if it does install I doubt you would get any level of support on crashes etc.

## This Book...

its part of a google book. It is what gave me the basic understanding.

The google search I used was sylvester dialytic elimination method

and the google book is Robot Analysis: The mechanics of serial and parallel Manipulators-

Hope the helps.

I do hope others reply to the original question. would polynomial ideals , grobner basis by useful here and if how to use them.

## Sylvester Matrix...

These 2 equations can be solved using the Sylvester Maxtrx technique. Have annotated the worhsheet to try and explain.

Would be interesting to see other techniques for solving them.

 Alternatively a Polynomial in h can be made   You need Numerical values for A,B,c,d,p to solve the polynomial Then back substitute the roots into one of the equations to get the corresponding values of g or h.   Test Values Back Substitution

## I would suggest you contact your supplie...

I would suggest you contact your supplier. I purchased a home use license of maple 15 early march and got a free upgrade to maple 16 when it was released. I just purchesed the home user license for maple 16 last week. I suppose by the time maple 17 and sim 7 are released I will need to pay something to get an upgrade.

## assign works now...

Thank you all for replys and comments. I did get assign to work. there was a duplicate entry ie 2 rows the same which caused the problem. To clarify a some of the ponts raised. The rows are dependant on the previous rows. I choose a matrix because in a previous post Iwas told lists can be inefficant. Also athe matrix is visually easy to read I find. What I posed was just a short made up example. Thr algsubs on the equations is to shorten them as the can go on for screenful after screenfull. At the end of the assembling the equations I end uo with a 4x4 matrix whose determinant multiplies out to a 20th order polynomial. It is at this point I am using the assign to the valuse saved in the store matrix. I shall experiment with the

"#If you prefer assignment then you can use the two elementwise operations assign~ and  =~  : assign~(store[..,1]=~store[..,2]): a1,CX3,S1; "

At present I am using a for i to 100 do loop.
