num2sci

Works just like num2str except will print with formatting in SI prefix notation.

Works just like num2str except will print with formatting in SI prefix notation and (optional) units and precision.

Works with arrays of numbers and (potentially) cell arrays of strings for the units, returning a cell array of strings.

Examples:

str = num2sci(165.48e-3) returns str = '165.5 m'
str = num2sci(165.48e-3,'V') returns str = '165.5 mV'
str = num2sci(165.48e-3,'mV') returns str = '165.5 uV'
str = num2sci(165.48e-3,3,'V') returns str = '165 mV'
str = num2sci([1.5 2.5],{'V','mA'}) returns str = {'1.5 V' '2.5 mA'}
