Description

Exponentiation of matrices or vectors by a constant vector.

If A is a vector or a rectangular matrix the exponentiation is done element-wise, with the usual meaning.

For square A matrices the exponentiation is done in the matrix sense.

For boolean, polynomial and rational matrices, the exponent must be an integer

Remark that 123.^b is interpreted as (123).^b. In such cases dot is part of the operator, not of the number.

Examples

2^4
[1 2;2 4]^(1+%i)
s=poly(0,"s");
[1 2 s]^4
[s 1;1  s]^(-1)
