how to determine if a variable has binary in matlab

To determine if a variable has binary in MATLAB you can use the isbinary function. This function returns true if all elements of the input argument are logical 0 or 1, and false otherwise. Here is an example:

main.m
x = [1 0 1 1]; % binary vector
y = [1 2 3 4]; % non-binary vector

isbinary_x = isbinary(x) % returns true
isbinary_y = isbinary(y) % returns false

In this example, isbinary_x returns true because all elements of x are either 0 or 1, whereas isbinary_y returns false because y contains non-binary elements (2, 3, and 4).
