Language and Programming

3-5

Compatibility Considerations

• Do not use the -f option to build engine and MAT-file applications. Use the -client

engine option instead.

• The format of the mex configuration files has changed. If there is a .bat or .sh

options file in the current or prefdir folder, MATLAB displays a warning. In a

future release, these warnings will become errors.

• Informational messages from mex have changed. The mex command displays the

selected compiler and success status. To suppress these messages, use the -silent

option.

• The output of the mex -setup command has changed. Use mex -setup to change the

default compiler for a given language. For more information, see Changing Default

Compiler.

• The mex -setup syntax has changed. You can specify a language. If none is specified,

mex -setup uses C.

Multidimensional array support for flipud, fliplr, and rot90

functions

The flipud, fliplr, and rot90 functions now support arrays with any number of

dimensions. These functions operate independently on the planes formed by the first and

second dimensions.

Option for circshift to operate on a specified dimension

The syntax circshift(A,K,dim) allows you to shift the elements of array A by K

positions along dimension dim. For more information, see the reference page for circshift.

Compatibility Considerations

The behavior of Y = circshift(A,K) for scalar K will change in a future release.

Currently, the function acts on the first dimension of A by default. In a future release, the

function will operate on the first dimension of A whose size does not equal 1 by default.

To retain current behavior, use circshift(A,[K 0]).

Changes to empty string matching with validatestring

validatestring now validates empty strings.
