- // Syntax: logm ( A )
-
- // Description:
-
- // The logm function computes the matrix natural logarithm. Logm uses
- // Parlett's method in the rfile funm.r.
-
- // Another way to compute logm (A) is to:
-
- // logm ( X ) = e.vec * log (e.val) / e.vec
-
- // See Also: expm, funm
- //-------------------------------------------------------------------//
-
- // Dependencies
