double

Converts A into double precision type.

Syntax

R = double(x)

Inputs

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

Outputs

R
Converted number.

Example

Basic example:
R = double(2.3)
R = 2.3
String example: 
double('test string')
R = [ 116 101 115 116 32 115 116 114 105 110 103 ]
Complex matrix:
R = double([2,3,8.2i-3.2,-5.1i])
R = [ 2, 3, -3.2 + 8.2i, -5.1i]
Complex number:
R = double(2i-9)
R = -9 + 2i

Comments

If a string is given, the string is converted into its ASCII value matrix. That matrix is then converted into double precision type.
