Loops and Conditional Statements

Control flow and branching using keywords, such as if, for, and while

Within any program, you can define sections of code that either repeat in a loop or conditionally execute. Loops use a for or while keyword, and conditional statements use if or switch. Additional keywords provide finer control over the program flow.

returnReturn control to invoking script or function
continuePass control to next iteration of for or while loop
pauseStop MATLAB execution temporarily
parforParallel for loop

Conditional Statements

To determine which block of code to execute at run time, use if or switch conditional statements.

Loop Control Statements

To repeatedly execute a block of code, use for and while loops.
