Function Modified Behavior
who, whos Displays information separately for nested functions
Compatibility Considerations
The following functions might, under certain circumstances, return a different value than
what was returned in MATLAB 7.0.4 (R14SP2):
datestr: Output might differ by 1 second from what was returned in a previous
version.
isfield: Output might differ if you used this feature in a release in which it was not
officially supported.
Evaluation Functions for Arrays, Structures, Cells
MATLAB offers the capability to apply a given function to each element of an array, each
field of a structure, or each cell of a cell array. See the help on arrayfun, structfun, and
cellfun for more information.
Using who and whos with Nested Functions
When you use who or whos inside of a nested function, MATLAB returns or displays
all variables in the workspace of that function, and in the workspaces of all functions
in which that function is nested. This applies whether you include calls to who or whos
in your M-file code or if you call who or whos from the MATLAB debugger. See thewho
reference page for more information.
Date and Time Functions Support Milliseconds
The datestr, datenum, and datevec functions now support time specification in
milliseconds. Use the symbol .FFF to represent milliseconds in any of these three
functions. See the table labeled Free-Form Date Format Specifiers on the datestr
reference page for more information.
Stack Trace Provided for lasterror
The lasterror function now returns an additional field in the structure that it returns.
The new stack field contains information from the stack on the M-file, function, and line
in which the error occurred.
