The CRAMER function solves an n by n linear system of equations using Cramer's rule.
This routine is written in the IDL language. Its source code can be found in the file
subdirectory of the IDL distribution.
Use this keyword to set the value of the floating-point zero. A floating-point zero on the main diagonal of a triangular array results in a zero determinant. A zero determinant results in a "Singular matrix" error and stops the execution of CRAMER. For single-precision inputs, the default value is 1.0 ¥ 10 -6 . For double-precision inputs, the default value is 1.0 ¥ 10 -12 .
