Function Name Use This Method Instead
dsearch DelaunayTri/nearestNeighbor
tsearch DelaunayTri/pointLocation
delaunay3 DelaunayTri
Compatibility Considerations
Update your code to use the DelaunayTri and TriScatteredInterp computational
geometry classes .
lsqnonneg No Longer Uses Optional Starting Point Input
The lsqnonneg solver no longer uses the optional input x0 as a starting point.
Compatibility Considerations
If you give a starting point x0, MATLAB issues a warning. Also, lsqnonneg ignores x0,
and instead uses a starting point of a vector of zeros.
Function erfcore Removed
Support for the erfcore function has been removed. Use of erfcore now results in the
following error message:
ERFCORE will be removed in a future release.
Use ERF, ERFC, ERFCX, ERFINV, or ERFCINV instead.
Compatibility Considerations
Replace erfcore with erf, erfc, erfcx, erfinv, or erfcinv. See the function reference pages
for the individual error functions.
Integer Warning Messages Removed
These warning messages for integer math and conversion have been removed:
• MATLAB:intConvertNaN
