MATLAB Programming

Using the Import Wizard
for you, select the Generate M-code checkbox in the lower right corner of
the Wizard dialog.
Once you click Finish to complete the import, MATLAB opens an Editor
window displaying the generated M-file function. The function is called
importfile.m. If this name is already taken, then MATLAB names the file
importfileN.m, whereN is a number that is one greater than the highest
existing importfile.m file.
The generated function has the following input and output arguments:
• Input: fileToRead1—Name of the file to import from. This argument
exists only when importing from a file.
• Output: newData1—Structure to assign all imported data to. This
argument exists only if you have specified an output argument with the
call to uiimport when starting the Import Wizard. Otherwise, variables
retain the same naming as assigned within the Wizard.
The newData1 output is a structure that has one field for each output of the
import operation.
The workspace variables created by this generated M-code are the same as
those created by running the Import Wizard. For example, if you elect to
format the output in column vectors when running the Import Wizard, the
generated M-file does the same. However, unlike the Import Wizard, you
cannot mark any variables to be excluded from the output.
Make any necessary modifications to the generated M-file function in the
Editor window. To save the M-file, select Save from the File menu at the top.
Caution You must save the file yourself; MATLAB does not automatically
save it for you.
