Intuitive Probability and Random Processes using MATLAB

Intuitive chance and Random strategies utilizing MATLAB® is an creation to likelihood and random methods that merges conception with perform. in accordance with the author’s trust that in basic terms "hands-on" adventure with the cloth can advertise intuitive figuring out, the procedure is to encourage the necessity for concept utilizing MATLAB examples, by means of idea and research, and eventually descriptions of "real-world" examples to acquaint the reader with a wide selection of functions.

Example text

9 Enabling M-Lint from the Preferences menu. 2 The MATLAB Environment 23 Red square Orange bar Red bar With cursor placed on red bar, this error message is displayed. 10 An example of M-Lint detecting two errors. In the error message, the designation “imbalance” refers to the omission of a right-most parenthesis, whose location has been underscored with a red line (darker shade). The message associated with the orange bar (lighter shade) indicates the omission of a semicolon at the end of the expression.

This can be done in two ways. 7. The second way is to use the cursor to highlight the lines of code that are to be indented and press ¿i (Ctrl and i simultaneously). 8. 7 21 Text pull-down menu in the Editor. The Editor also employs a color scheme. Keywords appear in blue, letters and numbers appearing between a pair of apostrophes are in violet, and comments appear in green. 8. Parentheses Grouping The Editor also keeps track of open and closed parentheses when typing a line of code. Every time a closed parenthesis is typed, the appropriate open parenthesis to the left is momentarily highlighted or underscored.

For this type of error, the program will execute. We see that in this case, line five does not end with a semicolon. For line six, the bar is red, which indicates that until the error is corrected, the program will not execute. To determine the error, one places the cursor over the bar, and the error message is displayed. In this case, it is indicating that a parenthesis is missing. The overall error status of the program is given by a colored square at the top of the right-hand column: green for no errors or warnings; orange for warnings, but no errors; and red for errors that prohibit program execution.
