READ CDF FILES IN MATLAB HOW TO

If save was used with -ASCII, the data is automatically tab delimited. Either command could have been issued with the keyword -ASCII. Although many other applications are now being created that can read and write this format, save and load can be used to both write and read text data which can make importing and exporting data a simple matter. The important points to remember in using save and load in this way is that MATLAB will by default attach the '.mat' extension to the data file and the file will be created or read from the current working directory.Īs stated earlier, this use of the save and load commands uses the default MATLAB binary file format. The following example shows just how simple this can be. The save command will save the specified data in MATLAB’s binary data format. If the data file was created in an earlier MATLAB session, simply issuing the load command with the filename is all that is needed. The load command can read either binary files containing matrices generated by earlier MATLAB sessions (usually by use of the save command), or text files containing numeric data. The most straightforward method of importing data is to use the load command. The following tables list the data formats for which MATLAB provides built-in support and the associated import commands. Modern MATLAB supports a broad range of standard data formats.

In many cases, you will be working with other MATLAB users and you will need to operate on their data.

However, before we consider data files from other applications, we should also understand how to import data saved during other MATLAB sessions. Once you have imported the data, you can then manipulate or plot the data. If you have a data file that was created using another application or program, the contents of that data file can be imported into the MATLAB workspace. Fortunately MATLAB provides a rich set of commands that support data input and output from many different standard formats. Whenever we are dealing with data in MATLAB, whether it is function generated, or measured, we are first faced with just how to bring that data into the MATLAB environment.
