hat
(^) exponentiation
Syntax
A^b
Description
Exponentiation of matrices or vectors by a constant vector.
If A
is a vector, the exponentiation is done
element-wise, with the usual meaning.
For a square A
matrix, the exponentiation is done in the matrix sense.
For boolean, polynomial and rational matrices, the exponent must be an integer.
Remarks
123.^b
is interpreted as (123).^b
. In such
cases dot is part of the operator, not of the number.
For two real or complex numbers x1
and
x2
the value of x1^x2
is the "principal value"
determined by x1^x2 = exp(x2*log(x1))
.
Exponentiation is right-associative in Scilab contrarily to Matlab® and Octave.
For example 2^3^4 is equal to 2^(3^4) in Scilab but is equal to (2^3)^4 in Matlab®
and Octave. |
Examples
2^4 (-0.5)^(1/3) [1 2;2 4]^(1+%i) s=poly(0,"s"); [1 2 s]^4 [s 1;1 s]^(-1)
