Matrix exponent computation

It's a generalizaton of a standard exponent e^x where x is a number. Matrix exponential is useful in some applying maths: multidimensional differential equations, control theory, etc.
We could compute it easily if we have Jordan decomposition, as illustrated in

Does it mean calculation of e^A where A is a matrix?

[SamoylovMD]

Correct. This designation means matrix series like standard representation for e^x.
