if statment in matlab

The basic syntax for an if statement in MATLAB is as follows:

main.m
if condition
    % code to execute if condition is true
end
60 chars
4 lines

condition is an expression that evaluates to either true or false. If condition is true, then the code inside the if statement is executed. If condition is false, then the code is skipped.

Here's a simple example:

main.m
x = 5;

if x > 0
    disp('x is positive')
end
47 chars
6 lines

This will print out x is positive because x is greater than 0.

You can also include an else statement to execute code if the condition is false:

main.m
x = -5;

if x > 0
    disp('x is positive')
else
    disp('x is not positive')
end

8 lines

This will print out x is not positive because x is not greater than 0.

You can also include elseif statements to check additional conditions:

main.m
x = 0;

if x > 0
    disp('x is positive')
elseif x < 0
    disp('x is negative')
else
    disp('x is zero')
end
