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.

MATLAB Language Syntax

`if, elseif, else`	Execute statements if condition is true
`switch, case, otherwise`	Execute one of several groups of statements
`for`	`for` loop to repeat specified number of times
`while`	`while` loop to repeat when condition is true
`try, catch`	Execute statements and catch resulting errors
`break`	Terminate execution of for or while loop
`return`	Return control to invoking script or function
`continue`	Pass control to next iteration of `for` or `while` loop
`pause`	Stop MATLAB execution temporarily
`parfor`	Parallel `for`-loop
`end`	Terminate block of code or indicate last array index

Topics

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.
