Stateflow problem with array contains structs

we have this matlab code:

    function od  = initOD
    % struct entry erstellen
    subEntry.access=3;  % 0=r/w  1=w 2=r 3=nicht belegt
    subEntry.value=NaN;

    entry.index=0;
    entry.subindex = [subEntry];

    % array aus entry structs erstellen
    od = [entry];

    % entrys befuellen
     od(1).index =hex2dec('1000');
     od(1).subindex(1).value=131478;
     od(1).subindex(1).access=2;

     od(2).index =hex2dec('1001');
     od(2).subindex(1).value=0;
     od(2).subindex(1).access=2;

     od(3).index =hex2dec('1008');
     od(3).subindex(1).value='device';
     od(3).subindex(1).access=2;

     od(4).index =hex2dec('1008');
     od(4).subindex(1).value='device';
     od(4).subindex(1).access=2;

     od(5).index =hex2dec('1016');
     od(5).subindex(1).value=1;
     od(5).subindex(1).access=2;
     od(5).subindex(2).value=0;
     od(5).subindex(2).access=0;

     od(6).index =hex2dec('1016');
     od(6).subindex(1).value=0;
     od(6).subindex(1).access=0;

     od(7).index =hex2dec('1018');
     od(7).subindex(1).value=1;
     od(7).subindex(1).access=2;
     od(7).subindex(2).value=1; % Vendor ID
     od(7).subindex(2).access=2;

     od(8).index = hex2dec('1F80');
     od(8).subindex(1).value=NaN; %NMT Startup
     od(8).subindex(1).access=0;

is it possible to run this funktion in stateflow? we are using structs because of code generation. It has to be compatibel with code generation. one of the error is this:

Class mismatch (double ~= struct).
The class to the left is the class of the left-hand side of the assignment.

Function 'initOD' (#767.201.203), line 10, column 1:
"od"
Launch diagnostic report.

We are blody beginners don´t know how to handle this.
