Why do I receive an error when using the DEC2HEX function in MATLAB 7.0 (R14)?

When I type the following code:

dec2hex([[2,3,4];[7,8,9]])

I receive the following error:

 ??? Operands to the || and && operators must be convertible to logical      

 scalar values. Error in ==> dec2hex at 23 if ~isreal(d) || any(d < 0) ||    

 any(d ~= fix(d))

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in MATLAB 7.0 (R14) in the way that the DEC2HEX function handles matrix data.

Currently, to work around this issue, use the following code:

x=[[2,3,4];[7,8,9]];

dec2hex(x(:))
