Spreadsheet Tools for Linear Equations

The ubiquitous (and potentially dangerous!) spreadsheet doe not have a standard facility fo solving sets of linear algebraic equations. However, since these, if well posed, do have an analytical solution, it is possible to program thhis into spreadsheet cells. Since the solution is very cumbersome, and impractical to produce manually, we have produced a program to generate it.

Preprogrammed spreadsheets are available for the following sizes of equation set:
.slk format - 2 ; 4 ; 6 ; 12 ; 18 ;

.xls format - 2 ; 4 ; 6 ; 12 ; 18 ;

You can use a larger solver than actually required by leaving extra equations as `xi = 0'.

There is also an online facility to generate spreadsheets here.
