If in response to the prompt you enter a vector using MATLAB syntax, that is surround the answer with square brackets, then this vector will be assigned to the output
So for example
z = input('please enter the vector: ')
This is what a typical result of running this code would look like
please enter the vector: [1 2 3 4]
z =
1 2 3 4
or
please enter the vector: [1;2;3;4]
z =
1
2
3
4
>>
You can then do what you want with each element of the vector that is returned.
For your specific example you could have your script or function include something like
z = input('enter values for A and B: ')
A = z(1)
B = z(2)
