Compatibility Considerations
If you are running MATLAB on a 64-bit computer system and you attempt to save a
variable that is too large for a version 7 (or earlier) MAT-file, that is, you save without
using the -v7.3 option, MATLAB skips that variable during the save operation and
issues a warning message to that effect.
If you are running MATLAB on a 32-bit computer system and attempt to load a variable
from a -v7.3 MAT-file that is too large to fit in 32–bit address space, MATLAB skips
that variable and issues a warning message to that effect.
Import Wizard Generates Import M-Code
The Import Wizard now includes an automated M-code generation option. Click the
Generate M-code button located in the lower right of the Import Wizard window and
MATLAB generates an M-file that you can use to import additional files that are similar
in type to the file you are currently importing. This simplifies the process of importing
multiple files into MATLAB.
New Dynamic Regular Expression Syntax
The new (?@cmd) operator specifies a MATLAB command that regexp or regexp is to
run while parsing the overall match expression. Unlike the other dynamic expressions
in MATLAB, this operator does not alter the contents of the expression it is used in.
Instead, you can use this functionality to get MATLAB to report just what steps it's
taking as it parses the contents of one of your regular expressions. This can be helpful in
debugging regular expressions, for example.
New Reserved MATLAB Keywords
Two new reserved keywords have been added to the MATLAB language in this release:
