Hi everyone, in creating model.A in MATLAB, how do I model x(t-1) in the constraint below?

x(t) - x(t-1) = scalar value

where

x(t) - value of x at time t

x(t-1) - value of x at time t-1

Thank you.

  Hi Elvin,

  For these particular constraints, you have to define your matrix to have T columns and T-1 rows, where T is the number of x variables. Then set the diagonal marix entries to -1 and the upper off-diagonal entries to 1. For an example of how to define the A matrix, please refer to our MATLAB examples. In particular, you could have a look at the facility.m example.

  Best regards, 
  Jaromił
