Loop Statements and Vectorizing Code

The chapter introduces the concepts of counted ( for ) and conditional ( while ) loops. Many common uses such as summing and counting are covered using the programming method. Nested loops are also introduced. Some more sophisticated uses of loops such as error-checking and combining loops and selection statements are also covered. Finally, vectorizing code, by using built-in functions and operators on vectors and matrices instead of looping through them, is demonstrated. Tips for writing efficient code are emphasized, and tools for analyzing code are introduced.
