• Events – ListenAccess and NotifyAccess
With this release, you can specify values for these attributes only explicitly as either the
appropriate character string or a meta.class object returned by the ? operator, or a
cell array of character strings and/or meta.class objects. See Specify Access to Class
Members for more information.
Method Declared as Abstract and Private Now Errors
In previously releases, declaring a method as both Abstract and Access = private
did not cause an error. With this release, declaring a method both Abstract and
private causes an error.
Compatibility Considerations
If any of your class definitions declare a method as both Abstract and private, you
need to declare the method either as Abstract, which make the class abstract and
requires subclasses to implement the method with the declared syntax, or declare the
method Access = private, which means that only methods within the defining class
can call the private method.
Declaring a method as both Abstract and private is not supported.
New Capabilities for Writing Image Data to FITS Files
MATLAB now includes a function named fitswrite that you can use to write image data
to Flexible Image Transport System (FITS) files. You can also display the metadata
for all Header-Data Units (HDUs) in a FITS file using the fitsdisp function. (MATLAB
already supports reading FITS files using the fitsread function.)
In addition, MATLAB now includes a new package, called matlab.io.fits, containing
dozens of functions that provide access to the routines in the CFITSIO library. Using
these low-level functions, you can create FITS files, read data from FITS files and write
data to the files, using the CFITSIO library, version 3.27.
Access Data on Remote Servers Using the OPeNDAP Protocol
You can read data stored on remote servers using the OPeNDAP protocol capability of
the following MATLAB NetCDF functions:
