There are many different Matlab commands within Libisis. These include basic commands, such as taking the exponential of a dataset, through to integration and plotting commands. The following is an online user manual for the matlab interface of the Libisis software.
Overview
There are many different object types within Libisis used to store experimental data. Once an object is created, functions exist to manipulate the data contained within. The most common objects for plotting and data manipulation are IXTdataset_1d and IXTdataset_2d objects. All relevant data pertaining to a run can be stored in an IXTrunfile object. Data from many different file formats may be read into these objects for manipulation. Described below are many different functions for handling data.
Directory Structure
The functions are organised into a particular directorary structure outlined here.
Data Manipulation Functions
Input and Output Functions
These functions are used for importing data into Libisis and exporting data from Libisis into file formats.
Binary Operators
Binary operators such as +, -, *, etc. are used to perform arithmetic operations between datasets and/or numbers
Elementary Functions
Elementary functions such as sin, cos and tan can be used on datasets
Data Manipulation Functions
Data may also be manipulated by scaling, flipping etc.
Rebin Functions
Data may also be manipulated to be binned differently.

Special Functions
Special functions are provided, mainly for internal use, to convert datasets or change the properties of a dataset.
Graphics
Plot Commands
There are many different ways to plot datasets, these are all outlined here.
Pre-Emptive Formatting
Many properties can be set before a plot is made, for instance on a line plot, the line colour may be set before a plot is made
Retrospective Formatting
Most formatting is performed after a plot is made. This includes changing limits and
Other Commands
Some other commands are contained within the graphics package to facilitate the advanced user.
