Method on @sym: power (x, y) ¶

Operator on @sym: x .^ y ¶

Symbolic expression componentwise exponentiation.

The .^ notation can be used to raise each element of a matrix to a power:

syms x
A = [sym(pi) 2; 3 x]
  ⇒ A = (sym 2×2 matrix)
      ⎡π  2⎤
      ⎢    ⎥
      ⎣3  x⎦
A.^2
  ⇒ ans = (sym 2×2 matrix)
      ⎡ 2    ⎤
      ⎢π   4 ⎥
      ⎢      ⎥
      ⎢     2⎥
      ⎣9   x ⎦

It can also be used on two matrices:

A.^[1 2; 3 4]
  ⇒ ans = (sym 2×2 matrix)
      ⎡π   4 ⎤
      ⎢      ⎥
      ⎢     4⎥
      ⎣27  x ⎦
