Two Types of issorted Warnings Are Now Errors
In previous versions, the issorted function generated a warning for the following two
cases:
issorted(x), where x is a complex integer, and
issorted(x,'rows'), where x is an ND array
Using issorted on a Complex Integer
In this case, a statement such as the following
issorted(int8(complex(1,2)))
now issues the error message
??? Error using ==> issorted
ISSORTED on complex inputs with integer class is obsolete.
Please use ISSORTED(DOUBLE(X)) or ISSORTED(SINGLE(X)) instead.
Using issorted on an N-D Array
In this case, a statement such as
issorted(ones(3,3,3),'rows')
now issues the error message
??? Error using ==> issorted
X must be a 2-D matrix.
Compatibility Considerations
If any of your program code attempts to use either of these types of statements, this code
will now generate an error.
Possible Conflict with New Keyword: SPMD
This release introduces a new keyword, spmd, that, although used solely by the Parallel
Computing Toolbox (PCT), may cause conflicts with MATLAB users as well. See spmd
