Ch LAPACK is Ch binding to C LAPACK libraries and included in Ch Professional Edition.
C LAPACK is C code translated from Fortran 77 LAPACK using
Fortran to C conversion utility called f2c.
LAPACK
can be used
to solve systems of simultaneous linear equations, least-squares solutions
of linear systems of equations, eigenvalue problems, and singular value
problems.
The matrix factorizations (LU,
Cholesky, QR, SVD, Schur, generalized Schur) as well as
related computations such as reordering
of the Schur factorizations and estimating condition numbers
can also be performed. Dense and banded matrices are handled.
In all these areas, similar functionality is provided for
both real and complex matrices, in both float and double data types.

C programs, such as shown in
this example,
using functions in C LAPACK can run in
Ch Professsional Edition across platform without compilation.

The following documentations and links provide the detailed information
about LAPACK and C LAPACK.
