I asked on the help-gsl mailing list, and the status of the matrix exponential is that, while present in GSL, it is "not supported" due to lack of testing. If you would like to take up the issue of how to get it supported, I suggest you send email to the help-gsl list.

There are three functions gsl_linalg_matmult gsl_linalg_matmult_mod gsl_linalg_exponential_ss in /usr/include/gsl/gsl_linalg.h and the library, but apparently don't have any documentation. Are they in working order? Is there any documentation for them? Should it be included with the rest of the GSL documentation?
Hello,
Functions not documented in the manual are considered obsolete or unsupported. In particular gsl_linalg_exponential_ss is lacking any tests, so it is not supported.
