Interpreting CPLEX output in MATLAB environment

I'm using the CPLEX API on MATLAB environment to sove a LP, and I would like to know what is the meaning of the "algorithm" item on the output. Example:

      cplexstatus: 1
cplexstatusstring: 'optimal'
       iterations: 2909
        algorithm: 1
             time: 0.4380
          message: 'Function converged to a solution x.'

Actually, my original problem is that I'm solving the LP with two differents approaches:

lpmethod = 4 --> Forces to use the barrier method (interior points method)

lpmethod = 0 --> The solver chooses automatically the method to be used.

I wanna know which method CPLEX used when I put the automatic choice, and I think my answer relies on this "algorithm" item.

Link to the "lpmethod" documentation --> https://www.ibm.com/docs/en/icos/20.1.0?topic=parameters-algorithm-continuous-linear-problems

Thanks in advance!
