scaleSI

Scale a number to nearest SI unit prefix

Syntax

x_sc = scaleSI(x)
[x_sc scale] = scaleSI(x)
[x_sc scale prefix] = scaleSI(x)
[x_sc scale prefix prefix_fullname] = scaleSI(x)

Description

scaleSI scales the input x to use the nearest SI unit prefix while keeping 1000 > x > 1. For example, scaleSI(0.00001) would give x_sc = '10u', scale = 1e6, prefix = 'u', and prefix_fullname = 'micro'.

Inputs

`x`	number to scale

Outputs

`x_sc`	string of scaled input and prefix
`scale`	numeric scale factor
`prefix`	single character scale prefix
`prefix_fullname`	full SI name for prefix
