After this the ‘Save file as …’ window appears and the desired file location and file name should be typed respectively into the ‘Save in:’ and ‘File name:’ positions. For this the ‘Save As …’ option from the File menu should be chosen.

The script file should be saved after it has been written into the Editor Window. The M-Lint regime appears in the Editor Window by default and can be disabled by un-signing the ‘Enable integrated M-Lint warning and error messages’ check-box in the M-Lint option of the Preferences Window, which can be selected from the File in the Editor Window or in the Desktop menu. The changes it recommends – such as the one shown in this figure (addition of a semicolon) – need not be executed because we want to display the resulting value of the DNA volume, V_DNA. When the cursor is placed at this line the comment message appears (see Figure 4.2). When the analyzer detects an error or possibility of improvement, it underlines/highlights the text and a horizontal line appears on the message bar. A green indicator means no errors, warnings or possibility of improvements a red indicator means syntax errors have been detected and an orange indicator means warnings or possibility of improvements (but no errors). The bar is topped by the message indicator. In the latest MATLAB® version the Editor Window appears with a message bar (located on the right) of the so-called M-Lint analyzer, which detects possible errors, comments on them and recommends modifications for better program performance. In addition, some MATLAB® functions of numerical analysis that are frequently used in applied calculations are presented.įigure 4.2 Script file in the Editor Window.

MATLAB® has two types of files: script and function files. The remedy lies in writing all commands sequentially into a file, saving it and running it as necessary. This is inconvenient, and the reader who has perused the preceding chapters has undoubtedly experienced it. Moreover, every time a calculation needs to be repeated, all commands have to be retyped and re-entered. When one of the sequence commands needs to be corrected, all its predecessors have to be re-executed and the command then corrected, after which all subsequent commands must be repeated to obtain the final result. Another disadvantage of the Command Window is that correction is possible only on the last line executed. The commands discussed in previous chapters were executed in the Command Window they were not saved, and cannot be re-used. 4 Script, function files and some useful MATLAB® functions
