![]() In addition, you must use filenames that are supported by MATLAB version 4.įor more control over the format of the file, MATLAB provides other functions, as listed in See Also, below. Therefore, you cannot save structures, cell arrays, multidimensional arrays, or objects. With the v4 flag, you can only save data constructs that are compatible with versions of MATLAB 4. ![]() Therefore, it is advisable to save only one variable at a time. The values of all variables saved merge into a single variable that takes the name of the ASCII file (minus any extension).There is no information in the save file that indicates whether the value was originally a number or a character. Each MATLAB character in a character array is converted to a floating point number equal to its internal ASCII code and written out as a floating point number string.If you are using a program other than MATLAB to read the saved data this restriction can be relaxed. In order to be able to read the file with the MATLAB load function, all of the variables must have the same number of columns.Saving a complex double array causes the imaginary part of the data to be lost, as MATLAB cannot load nonnumeric data ( 'i'). Each variable to be saved must be either a two dimensional double array or a two dimensional character array.When saving in ASCII format, consider the following: The specified existed MAT-file, appended to the end Saves the workspace variables in the format specified by option For example, save('A*') saves all variables that start with A. Use the * wildcard to save only those variables that match the specified pattern. Saves only the specified workspace variables in filename.mat. ![]() If filename is the special string stdio, the save command sends the data as standard output. To save to another directory, use the full pathname for the filename. Stores all workspace variables in the current directory in filename.mat. They can also be manipulated by other programs external to MATLAB. They can be created on one machine and later read by MATLAB on another machine with a different floating-point format, retaining as much accuracy and range as the different formats allow. MAT-files are double-precision, binary, MATLAB format files. Save (MATLAB Functions) MATLAB Function ReferenceĪs an alternative to the save function, select Save Workspace As from the File menu in the MATLAB desktop, or use the Workspace browser.īy itself, stores all workspace variables in a binary format in the current directory in a file named matlab.mat.
