| Importing and Exporting Data Thefirst step in analyzingdataistoimport itintothe MATLAB® workspace. The Programming Fundamentals documentation provides detailed information about supported data formats and the functions for importing data into the MATLAB workspace. TheeasiestwaytoimportdataistousetheMATLABImportWizard, described in the Programming Fundamentals documentation. With the Import Wizard, you can import the following types ofdata sources: • Text files, such as .txt and .dat • MAT-files • Spreadsheet files, such as .xls • Graphics files, such as .gif and .jpg • Audioand videofiles,suchas .avi and .wav The MATLAB Import Wizard processes the data source and recognizes data delimiters, as well as row or column headers, to facilitate the process of data selection. After you finish analyzing your data, you might have created new variables. You can export these variables to a variety of file formats. The Programming Fundamentals documentation also describes how to export data from the MATLAB workspace. When working with time series data, it is easiest to use the Time Series Tools GUI to import the data and create timeseries objects. The Import Wizard in Time Series Tools also makes it easy to import or define a time vector for your data. | ||||||||
