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.

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.
