Why do I get an error when trying to compile STRFIND into a stand-alone program using the MATLAB Compiler?

When I try to compile a file containing STRFIND into a stand-alone executable using the MATLAB compiler, I get the following message:

 Warning: No M-function source available for "strfind", assuming

 function [varargout] = strfind(varargin)

 NOTE: This will produce a link error in stand-alone code

 unless you provide a hand-written definition for this function.

 Undefinedfirst referenced

symbol      in file

 mlfNStrfind                         test.o

 ld: fatal: Symbol referencing errors. No output written to test

     mbuild: link of 'test' failed.

 ??? Error using ==> mbuild

 Unable to complete successfully

 ??? Error: An error occurred while shelling out to mbuild (error code = 1).

 Unable to build executable (specify the -v option for more information).

The simple file that I tried to compile is:

function a = test

b = 'hello';

a = strfind(b,'l')

and I compiled it using MSVC and the following command:

mcc -m test.m -v

This is a bug in the MATLAB Compiler 2.2 (R12.1) that has been fixed in the MATLAB Compiler 3.0 (R13).

For previous versions, please try using the FINDSTR function rather than STRFIND. Documentation on FINDSTR can be found by typing the following at the MATLAB Command Prompt:

doc findstr
