Why do I get "Array indices must be positive integers or logical values" error when using "angle" function?
>> z = 22+i
>> a = angle(z)
>> z =
22.0000 + 1.0000i
ERROR: Array indices must be positive integers or logical values.

Based on the error message, it seems like you have a variable with the name "angle" stored in your workspace that overshadows the "angle" function

That code assumes that the values in Scores and Scores2 are all positive integers, and will give you an error if that is not the case.
That code also assumes that the Scores and Scores2 values are all either 1 or 2, but will not give an error if they are larger integers instead.

@Nguyen Quoc Khanh: t is not a nonzero integer. It can't be used for an index on the LHS of that assignment. You don't need to anyway.
s = cos(2*pi*100*t) + 2*cos(2*pi*200*t+pi/2) + 3*cos(2*pi*200*t+pi/4); % quá trình lấy mẫu
