Compiled executable doesn't recognize filter object (.m file works fine!)

Hi there,

When I run the following as a .m file, everything works. But the compiled executable version doesn't work.

load data_mat % loads the 'data_seg' variable

load filter_specs % loads the 'custom' filter object

filteredData = filter(custom,data_seg);

The filter object 'custom' has been created like this: Hd_custom = fdesign.bandpass(120,130,4000,4010,60,1,60,40000); custom=design(Hd_custom,'cheby2'); save('filter_specs.mat','custom')

The error that I receive is this:

Warning: Variable 'custom' originally saved as a dfilt.df2sos cannot be instantiated as an object and will be read in as a cell. > In filter_exe at 4 ans = file: [1x87 char] name: 'filter_exe' line: 18 ans = Undefined function 'filter' for input arguments of type 'cell'.

This is what I get when I run ver:

Any help would be greatly appreciated!

When an object is loaded from a .mat file compiler will not be able to analyze the dependencies needed to run the object saved in this .mat file. Try adding required functions using "%#function" in your code and then compiling it.

See documentation for %#function at http://www.mathworks.com/help/compiler/function.html.
