sbioregisterunit - Create user-defined unit

Note   sbioregisterunit has been removed and produces an error. Use sbiounit, followed by sbioaddtolibrary instead.

Syntax

sbioregisterunit('Name', 'Composition', Multiplier)
sbioregisterunit('Name', 'Composition', Multiplier, Offset)

Description

sbioregisterunit('Name', 'Composition', Multiplier) creates a unit with the name Name where the unit is defined as Multiplier*Composition and records the unit in the UserDefinedUnits vector of sbioroot and adds it to the user-defined library.

sbioregisterunit('Name', 'Composition', Multiplier, Offset) creates a unit with the specified offset. You can list available units with the sbioshowunits function.

• Name is the name of the user-defined unit. Name must begin with characters and can contain characters, underscores or numbers. Name can be any valid MATLAB variable name.

• Composition shows the combination of base and derived units that defines the unit Name. For example molarity is mole/liter. Base units are the set of units used to define all unit quantity equations. Derived units are defined using base units or mixtures of base and derived units.

• Multiplier is the numerical value that defines the relationship between the unit Name and the base unit as a product of the Multiplier and the base unit. For example 1 mole is 6.0221e23*molecule. The Multiplier is 6.0221e23.

• Offset is the numerical value by which the unit composition is modified from the base unit. For example °Celsius = (5/9)*(°Fahrenheit-32); Multiplier is 5/9 and Offset is –32.
