Calculates e^A
for a square, full rank matrix A
. The syntax for its use is
y = expm(A)
Internally, expm
is mapped to a simple e^A
expression (which in turn uses the eigenvalue expansion of A
to compute the exponential).
An example of expm
--> A = [1 1 0; 0 0 2; 0 0 -1] A = 1 1 0 0 0 2 0 0 -1 --> expm(A) ans = 2.7183 1.7183 1.0862 0 1.0000 1.2642 0 0 0.3679
