#define PARTIAL_INP_INDEX (  eye, x    )     ((eye)*(RN*RN)+(x)*(RN))

Wrappers to hide input vector index calculations to a given location (x,y) on a given eye:. index(eye,x,y) = eye*RN*RN + x*RN + y The first term should be optimized out by any decent compiler if eye=0, and it should be precomputed by the compiler if eye=1. The second term can be optimized out of loop calculations by precomputing the partial index below, and then adding in the last term inside the loop using FULL_INP_INDEX. Given the index `idx' for a location in the first eye, the index for the same location in another eye may be obtained using INP_INDEX_OTHER_EYE(idx,eye). Definition at line 88 of file kernel.h.

#define PARTIAL_LAT_INDEX (  ui, uj, k, radius, width    )     (((k)-(ui)+(radius))*(width)-(uj)+(radius))

Wrappers to hide lateral connection index calculations for a given unit (ui,uj):. index(k,l) = (k-(ui-radius))*array_width + l - (uj-radius) The first term and last terms can be optimized out of loop calculations by precomputing the partial index below, and then adding in the middle term inside the loop using FULL_LAT_INDEX. Definition at line 32 of file kernel.h. Referenced by LissomMap::lat_resp(), LissomMap::modify_latwt_loop(), and LissomMap::reduce_lateral_radius().
