If filename is a MAT-file, then load filename loads variables from the file; if filename is an ASCII file, then load filename loads a double-precision array containing data from the file. Security Considerations: The load command might execute code contained in a MAT-file as it initializes variables. Avoid calling load on untrusted MAT-files. If filename is a MAT-file, then S is a structure array; if filename is an ASCII file, then S is an m -by- n double-precision array containing data from the file, where m is the number of lines in the file and n is the number of values on each line. Command form requires fewer special characters. You do not need to type parentheses or enclose the input in single or double quotes.

To save a subset of your workspace variables to a MAT-file, select the variables in the Workspace browser, right-click, and then select Save As. You also can drag the selected variables from the Workspace browser to the Current Folder browser. Variables that cannot be saved to a script are saved to a MAT-file with the same name as that of the script. You also can save workspace variables programmatically using the save function. For example, to save all current workspace variables to the file june To store fields of a scalar structure as individual variables, use the save function with the -struct option. To save part of a variable, use the matfile function. This can be useful if you are working with very large data sets that are otherwise too large to fit in memory.

In addition to plotting values created with its own commands, MATLAB is very useful for plotting data from other sources, e. Typically this data is available as a plain text file organized into columns. MATLAB can easily handle tab or space-delimited text, but it cannot directly import files stored in the native binary format of other applications such as spreadsheets. Unfortunately, the load command requires that your data file contain no text headings or column labels. Below I demonstrate both approaches with examples. I've included an m-file to handle the more complex case of a file with an arbitrary number of lines of text header, in addition to text labels for each column of data. Though hardly a cure-all, this function is much more flexible than the load command because it allows you to provide documentation inside your data file. The simplest, though least flexible, procedure is to use the load command to read the entire contents of the file in a single step. The load command requires that the data in the file be organized into a rectangular array.
