log2

Computes the base-2 logarithm of a matrix.

Syntax

R = log2(x)

[F,E] = log2(x)

Inputs

x
Any valid scalar | vector | matrix
Type: double | integer | char | string | logical | struct | cell
Dimension: scalar | vector | matrix

Outputs

R
Resulting scalar | vector | matrix. A resulting matrix has the same dimensions as x.
F,E
X = F.*2.^E

Examples

Scalar input:
R = log2(2)
R = 1
Scalar input with multiple return:
[F,E] = log2(140)
F = 0.546875
E = 8
