if statement in matlab

In Matlab, the if statement is used for conditional execution of code. It follows the general syntax:

main.m
if *condition*
    *code to execute*
end
41 chars
4 lines

Here, the condition must be a logical expression that evaluates to true or false. If the condition is true, then the code between the "if" statement and the "end" keyword will be executed. If the condition is false, then the code block will be skipped.

For example, the following code will check if a variable 'x' is greater than 10, and if it is, it will display a message:

main.m
x = 15;
if x > 10
    disp('x is greater than 10');
end

Output:

main.m
x is greater than 10

You can also include an optional "else" keyword which allows you to specify code to execute when the condition is false:

main.m
if *condition*
    *code to execute if condition is true*
else
    *code to execute if condition is false*
end

For example, the following code will check if a variable 'y' is odd or even, and display a message accordingly:

main.m
y = 7;
if mod(y,2) == 0 
    disp('y is even');
else
    disp('y is odd');
end
