## EXPM Matrix Exponential

Section: Array Generation and Manipulations

### Usage

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).

### Example

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
