Steps for Using File Exchange

Open the tool by selecting Desktop > File Exchange.
In the login window, provide the e-mail address and password for your MathWorks Account.
For more information, see What You Need to Use File Exchange.
After logging in, File Exchange displays:
- The most popular tags for all files in the repository. Tags are keywords that users associate with files. The more frequently users apply a tag, the more popular it is.
- The 50 most recently submitted files
Find files. In general, the most efficient way to begin is by entering search words.
For more information, see Finding Files in File Exchange — Searching and Using Tags.
Refine results by selecting relevant tags, which you can see in cloud or list view. In cloud view, the font size of the tag indicates its popularity.
For more information, see Using Tags to Find Files in File Exchange.
Look for files you want to use. If you do not see any files you want, see other results by changing the sort order, the search words, or the selected tags. File Exchange lists up to 50 different files.
For more information, see Viewing and Sorting the List of Files in File Exchange.
View more details about a file by clicking the file name in the list of files. The file details page opens.

Example — Finding and Downloading a File in File Exchange

This example looks for files to help you analyze voice signals.

Note The File Exchange repository changes daily. Your results could differ from this example.

Select Desktop > File Exchange, and log in to your MathWorks Account.
File Exchange:
- Shows the most popular tags for all files in the repository. For the example, the most popular tags are data export, data import, etc.
- Lists the 50 most recently submitted files, with 10 files per page. For the example, the most recently submitted file is flattin/merging nested cells.
- Reports the total number of files in the repository accessible to File Exchange in the desktop (have a BSD license). For the example, there are 3,901 files.
Type signal in the search field.
File Exchange:
- Reports that 277 files contain signal or variations of it in the title, tag, or description.
- Lists 50 of the 277 matches, with the most recently submitted, Find and Replace, at the top of page 1.
- Shows the most popular tags associated with the 50 files listed: aerospace, automotive, etc.
For more information, see Using Search to Find Files in File Exchange.
Because there are no obvious results or tags of interest, change the criteria. Change the sort order to show results that have the highest ratings first by clicking the Rating column header.
File Exchange:
- Lists the 50 highest rated files among the 277 matches. The most highly rated result is Status / progress indicator.
- Shows the most popular tags associated with the 50 files listed.
  - The audio processing tag is now among the most popular.
  - The automotive tag is no longer among the most popular tags for the 50 files listed.
For more information, see Sorting the List of Files in File Exchange.
Narrow the results by selecting the audio processing tag.
File Exchange:
- Reports that 20 files are associated with the audio processing tag or variations of it, and have signal in the title, tag, or description.
- Shows the popular tags associated with the 20 files listed.
For more information, see Finding Files Using Tags.
Scroll through the list of files on the first page. Speech Analysis using LPC looks like it could be useful. Select the file name in the list of files.
File Exchange replaces the list of files with the details page for Speech Analysis using LPC. On the details page, view additional information to decide if you want to use the file. For example, the details page reports that the file requires the Data Acquisition Toolbox™ and Signal Processing Toolbox products. For more information, see Viewing Details About a File.
Download the file to the current folder:
1. In the details page, open the menu on the Download button.
2. From the button menu, select Download to Current Folder.
For more information, see Downloading Files from the File Exchange Repository.
In the resulting confirmation dialog box, click Download.
When the download completes, File Exchange reports the list of files and download location. Click Change to Containing Folder to access the files.
Go to the Current Folder browser. The current folder is simplelpcgui and contains the files you downloaded. Open the simplelpcgui.m file to review it. You can run the file. For more information, see Best Practices for Using Files Provided by Other Users.
