In mat-lab transmission line parameters, "The resistance r per unit length, as an N-by-N matrix in ohms/km" what is N by N matrix in this case?

From the documentation https://www.mathworks.com/help/physmod/sps/powersys/ref/distributedparameterline.html:
"Resistance per unit length"
"The resistance r per unit length, as an N-by-N matrix in ohms/km (Ω/km). Default is [0.01273 0.3864]."
"For a symmetrical line, you can either specify the N-by-N matrix or the sequence parameters. For a two-phase or three-phase continuously transposed line, you can enter the positive and zero-sequence resistances [r1 r0]. For a symmetrical six-phase line you can enter the sequence parameters plus the zero-sequence mutual resistance [r1 r0 r0m]."
"For asymmetrical lines, you must specify the complete N-by-N resistance matrix."
You need to know if your transmission line is symmetrical or asymmetrical. If you are not sure then it is probably symmetrical.
