Hi I've tried to create an executable in vain.
1) Here is the code in the m file:
<CODE>
function fixedPointHexNumber = fixedPointHexNumber(number, hexDigits, fixedPointFractional)
if str2num(fixedPointFractional) >= str2num(hexDigits)*4
fixedPointHexNumber = 'ERROR: Fractional part cannot be greater or equal (due to sign bit) to hexDigits*4';
else
fiNumber = fi(str2double(number), true, str2num(hexDigits)*4, str2num(fixedPointFractional));
intfiHexNumber = fiNumber.hex();
fixedPointHexNumber = sprintf(intfiHexNumber);
end
</CODE>

I used the following to create the executable:
mcc -m -d ./matlab_compiled/ fixedPointHexNumber

When I tried to run the executable in a command prompt, I get the following:
??? Undefined function or method 'fi' for input arguments of type 'double'.
Error in ==> fixedPointHexNumber at 5
MATLAB:UndefinedFunction

I am a newb at matlab and completely lost.

Thanks for any help,
Amish

Take a look at this line in your code:

fiNumber = fi(str2double(number), true, str2num(hexDigits)*4,
str2num(fixedPointFractional));

Can you tell me what fi() is? Is it a function, or a variable? Well
neither I, nor the executable seem to know.

Sounds like something from the Fixed-Point Toolbox.

"ineligible for use on" the matlab compiler.

Thanks a lot,
I didn't realize some toolboxes could not be used with the compiler.
