For skipping lines under a certain condition, you can also use an if statement.

It is my understanding that you want to go to some particular line of code. However, MATLAB does not support "C style goto statements". If you wish to skip some particular lines of code, you can use "continue" function in MATLAB, or, if you wish to go to a particular line in a code after executing a loop, you can use "if" condition.

Here is a sample code:

res = 0;
arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];
for i=1:9
    rem = mod(arr(i), 2);
    % Checks if element of array "arr" is odd, then it do not add the element to "res" variable.
    if rem == 1
        continue;
    end
    res = res + arr(i);
end
% After loop end, checks if "res" is greater than 30 or not, to goto specific line of code.
if(res > 30)
    res = res - 5;
else
    res = res + 5;
end
Displays the value of res
disp(res);
