// 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
require funm
logm = function ( X )
{
return funm (X, log)
};
