MATLAB Programming 31 - if...elseif...elseif...else statement

if...elseif...elseif...else...end Statements

An if statement can be followed by one (or more) optional elseif... and an else statement, which is very useful to test various conditions.

When using if... elseif...else statements, there are few points to keep in mind:

An if can have zero or one else's and it must come after any elseif's.
An if can have zero to many elseif's and they must come before the else.
Once an else if succeeds, none of the remaining elseif's or else's will be tested.

Syntax

if <expression 1>          % Executes when the expression 1 is true

<statement(s)>

elseif <expression 2>    % Executes when the boolean expression 2 is true

<statement(s)>

Elseif <expression 3>   

% Executes when the boolean expression 3 is true

<statement(s)>

else                                

% executes when the none of the above condition is true

<statement(s)>
