1. A method comprising:
- determining a transimpendance matrix for a plurality of electrodes that are part of a hearing prosthesis;
performing a matrix inversion of the transimpedance matrix to obtain a transadmittance matrix for the plurality of electrodes;
generating an adjusted transimpedance matrix comprised of the transimpedance matrix having a diagonal that is modified based on positive off-diagonal values of the transadmittance matrix;
calculating, using the adjusted transimpedance matrix, corresponding weights for the plurality of electrodes for a stimulation channel; and
providing the calculated weights to the hearing prosthesis; and
using the calculated weights to deliver stimulation to a recipient of the hearing prosthesis via one or more of the plurality of electrodes.
