 This calculator solves a system of linear equations in the form A*X=B
where A is the m x n
matrix containing the coefficients of the unknowns and B is
a matrix with m rows containing the righthand side terms.
 B can have more than one column; in this case X will
be computed for multiple righthands and will have the same as many columns
as B.
 If m<n, then the system
is underdetermined and a least norm solution is returned.
 If m=n and A
in nonsingular then the unique exact solution is returned. If A
is found to be singular, a lest norm solution is returned.
 If m>n then the system is
overdetermined and the least squares solution is returned.
 Use spaces, tabs or commas as delimiters between matrix elements.
 You can copy and paste values from an Excel spreadsheet. In this case you will need
to specify that the values are delimited by tabs.
 Valid entries are numbers such as: 1234.5677, 1.23E10, 1.E10
 Matrices of up to 30 rows by 30 columns
can be entered. If you enter larger matrices, extra rows or columns will be ignored.
