Claim One:
1. A method for determining weights for a stimulation channel of a stimulating hearing prosthesis having a plurality of electrodes, wherein the stimulation channel uses the determined weights in providing stimulation using a plurality of the electrodes of the stimulating medical device, the method comprising: determining a transimpedance matrix for the plurality of electrodes; computing a transadmittance matrix for the plurality of electrodes, the transadmittance matrix being a matrix inversion of the transimpedance matrix; computing an error based on positive off-diagonal values of the transadmittance matrix; determining if the error exceeds a criterion level; adjusting a diagonal of the transimpedance matrix if the criterion level is exceeded; calculating the corresponding weights for the plurality of electrodes for the stimulation channel using the adjusted transimpedance matrix; and providing the calculated weights to the stimulating medical device for use in providing stimulation to a recipient of the stimulating medical device.
