If you do not specify the LIBRARY= option, formats are stored in a default format catalog named Work.Formats. As the libref Work implies, any format that is stored in Work.Formats is a temporary format that exists only for the current SAS session.
Data Processing and Visualization Topic Skills Importing Data • Import a mixture of data types from text files using the textscan function • Use low-level I/O functions to read data from a file • Describe techniques to import files with large data sets or irregular formats • List MATLAB functions that help you to manage the files that you read and write • Export a mixture of data types to text files using the fprintf function Organizing Data • Extract multiple data elements from a cell array • Create a structure array to store data organized by field names • Extract data from a structure into an array of values • Create an anonymous function and apply it to each cell in a cell array or each field within a structure • Locate, count, and extract array elements meeting a given criteria Visualizing Data • Select the type of MATLAB plot that is appropriate for the given data and application • Generate customized plots using MATLAB code • Obtain handles to graphical objects as output or using querying functions • Use the get and set commands to further customize a generated MATLAB plot • Navigate the Handle Graphics Property Browser to find documentation on the graphics object and property that affect a specific characteristic of a plot Programming Creating Robust Applications • Call query functions to validate function inputs • Implement a try-catch construct, along with MException objects , for handling error conditions • Ensure code provides desired results by using integrated MATLAB code analysis and debugging tools • Measure code performance using MATLAB Profiler and other tools • Describe the concept of numerical accuracy Structuring Code • Select an appropriate type of MATLAB function based on requirements for function visibility and workspace access • Create and call an anonymous function handle to change the interface to an existing function • Determine which function a program will call when multiple possibilities exist Structuring Data • Write code for preallocating various types of arrays • Use vectorization techniques to improve code performance • Explain memory usage when passing arrays to functions • Minimize memory requirements for an application by selecting the most appropriate data type Classes and Objects • Describe the benefits of writing a MATLAB class • Write a class for a custom data type with properties and methods • Create an instance of the class in the code and invoke its methods • Describe the difference between a value class and a handle class • Override common MATLAB functions for a given class using methods Graphical User Interfaces Handle Graphics • State the layers in the graphical object hierarchy in MATLAB • Create a Handle Graphics object • Obtain a handle to a graphics object • Determine Handle Graphics object properties and acceptable values Modify properties of a graphics object using property name/property value pairs Components of a GUI Application • Add a UI control , such as a push button, to a MATLAB figure window • Specify the behavior of a UI control by associating it with MATLAB code • State the order of execution of the GUI code throughout the lifetime of the application Programming Considerations for GUI Applications • Write a function for use as a GUI callback • Pass user-defined data into callback functions • Organize GUI creation code and callbacks into a single MATLAB file • Organize object handles to facilitate passing them into callbacks Layout of GUI Applications Using GUIDE • Use GUIDE to lay out GUI objects • Assign unique names to GUI objects using the Tag property • Modify the layout and properties of GUI objects created by GUIDE • Modify the behavior of GUI objects created by GUIDE Programming GUI Applications Using the GUIDE Template • Use the handles structure created by GUIDE to manipulate graphics objects within a callback • Write callbacks that can communicate with each other by adding local data to the GUI URL: http://www.mathworks.com/services/training/courses/MCMP_4.html
