Creating a New M-File in the Editor/Debugger

To create a new M-file in the Editor/Debugger, either click the new file button on the MATLAB toolbar, or select File -> New -> M-file from the MATLAB desktop. You can also create a new M-file using the context menu in the Current Directory browser--see Creating New Files. The Editor/Debugger opens, if it is not already open, with an untitled file in the MATLAB current directory from which you can create an M-file.

If the Editor/Debugger is open, create more new files by using the new file button on the toolbar, or select File -> New -> M-file.

Function Alternative

Type edit in the Command Window to create a new M-file in the Editor/Debugger. Type edit filename.m to open the M-file filename.m in the Editor/Debugger.

If filename.m does not exist, a prompt appears asking if you want to create a new file titled filename.m.

• If you click Yes, the Editor/Debugger creates a blank file titled filename.m. If you do not want the dialog to appear in this situation, select that check box in the dialog. Then, the next time you type edit filename.m, the file is created without first prompting you. If you later want that dialog to appear, specify it in preferences for Prompt.
• If you click No, the Editor/Debugger does not create a new file. If you do not want the dialog to appear in this situation, select that check box in the dialog In that case, the next time you type edit filename.m, a "file not found" message appears. If you later want that dialog to appear, specify it in preferences for Prompt.
