if condition

This control structure checks the expression provided in parenthesis is true or not. If true, the execution of the statements continues. Syntax :

if (condition)
    statements
    ...
    ...
end 
(endif can also be used)

Example : 

MATLAB




% initializing variables variable1 and variable2
variable1 = 20;
variable2 = 20;
  
% check the if condition
if variable1 == variable2,
  
% if the condition is true this statement will execute
disp('The variables are Equal');
 
% end the if statement
endif;


Output:

The variables are Equal

Loops (For and While) and Control Statements in Octave

Control statements are expressions used to control the execution and flow of the program based on the conditions provided in the statements. These structures are used to make a decision after assessing the variable. In this article, we’ll discuss control statements like the if statement, for and while loops with examples.
