Data Type Change to Output Variable for bwdist
The bwdist function returns two output variables: the Euclidean distance transform and
the closest-pixel map. The data type of the second output variable, the closest-pixel map,
has changed.
Compatibility Considerations
Before R2012a, the data type of the second output variable returned by the bwdist
function was single. Now the data type of the second output variable returned by
bwdist is dynamically chosen.
iradon Function Updated
A small imprecision in the way the dc level was computed in iradon has been corrected.
Compatibility Considerations
Output variables I and H will be slightly different (about 1% to 2%) than in previous
versions.
