Error in .exe but not in .m

Hello,

I've generated an executable file from an matlab script using the deploytool of Matlab (type: Console application).

When I run the code in Matlab there are no errors. However, when I run the .exe file, with the same inputs, from cmd I got an error: "Matrix dimensions must agree". Below I show you the code which generated the error:

Vignetting(Vignetting<=threshold)=0;

I have tried to replace this line by:

        idx=find(Vignetting<=threshold);
        Vignetting(idx)=0;

But once again, I got the error "Matrix dimensions must agree" when I run the .exe

Why do I get this error in the .exe file and in Matlab the code works well? How can I solve this problem (recommendations)?

Thank you very much in advance,

Without seeing the code I can only guess, but is threshold one of the input arguments to the function from which you generated the executable? If so, read the next-to-last section in the documentation page describing how input arguments are passed into standalone applications. My guess is that you're passing in a threshold of something like 0.1 which is treated as the char vector '0.1' not the number 0.1.

Put these lines before that line

whos Vignetting
whos threshold

What does it show you? Is threshold a scalar or an double array, or a string? How did you set threshold?

Also, see the FAQ: http://matlab.wikia.com/wiki/FAQ#My_standalone_executable_won.27t_run_on_the_target_computer._What_can_I_try.3F

In fact, threshold is an input argument. I should have converted this variable in a numeric number:

threshold=str2num(threshold);

Now, it is working.

Thank you very much.
