1. A method of stimulating tissue using a plurality of electrodes, comprising:

  • determining desired electrical parameter values at a plurality of spatial points;

    selecting a plurality of constituent current sources adjacent the locations of the electrodes;

    determining the relative strengths of the constituent current sources that, when combined, result in estimated electrical parameter values at the spatial points that best matches the desired electrical parameter values at the spatial points;

    selecting the polarity and percentage of electrical current to be associated with each of the electrodes based on the determined strengths of the constituent current sources; and

    conveying electrical current through the plurality of electrodes in accordance with the selected electrical current magnitudes to stimulate the tissue.
