not an integer in matlab

To check if a variable is not an integer in MATLAB, you can use the isnumeric function and check if the variable is not only numeric but also not an integer. Here's an example code snippet:

main.m
x = 2.5; % variable to check
if isnumeric(x) && ~isinteger(x)
    disp('Variable is not an integer')
else
    disp('Variable is either not numeric or an integer')
end

In this code, we first check if the variable x is numeric using isnumeric. Then, we check if x is not an integer using the ~ operator and the isinteger function. Finally, we display a message to indicate if the variable is not an integer or if it's not numeric or an integer.
