Compatibility Considerations

If you have a program that calls another program with nonmatching letter case, the call

to this function now throws an error.

New narginchk Function Replaces nargchk

narginchk is a new function that replaces and adds to the functionality of nargchk.

The narginchk function differs from nargchk in the following ways:

• narginchk accepts only 2 inputs: the minimum and maximum allowable number of

arguments one can pass to the currently running function.

• narginchk returns no outputs. Instead, it throws an error if the number of

arguments passed to the current function is outside the allowable range

Conversion of Error and Warning Message Identifiers

For R2011b, error and warning message identifiers have changed in MATLAB.

Compatibility Considerations

If you have code that uses message identifiers that changed, you must update the code

to use the new identifiers. Typically, message identifiers are used to turn off specific

warning messages, or in code that uses a try/catch statement and performs an action

based on a specific error identifier.

For example, the MATLAB:eigs:NonPosIntSize identifier has

changed to MATLAB:eigs:RoundNonIntSize. If your code checks

for MATLAB:eigs:NonPosIntSize, you must update it to check for

MATLAB:eigs:RoundNonIntSize instead. For a mapping of the new identifiers to the

original identifiers, see Technical Support solution 1-ERAFNC.

New Spreadsheet Import Tool

The new Spreadsheet Import Tool allows you to select ranges of data and define rules

for handling nonnumeric values. This tool opens instead of the Import Wizard for

spreadsheets and comma-separated value (CSV) files. For more information, watch this

video demo.
