Matlab code to java using shared library

Hi! I have a very special problem in matlab and I really hope you can help me. I try to run my matlab script with shared library compiler on computers without matlab. I have followed the introduction: https://de.mathworks.com/help/compiler_sdk/gs/create-a-java-application-with-matlab-code.html exactly but I have the problem that my function requires an image, not a number! Here is my code:

if true
  function [F,C]=factorImage3a(d_pp)

    %name='/Users/name/archive/speichel.dcm';
    %info=dicominfo(name);

    matrix=128;
    nf=2;
    ni=100;

   %d_pp=dicomread(h);
   %--------------------------------------------------------------------------
   is=matrix;                                                        % image size
np=is*is;                                                % number of pixels
%--------------------------------------------------------------------------
% convert images to vectors
v=zeros(np,1);
d=zeros(np,ni);
for i=1:ni
    v(:)=d_pp(:,:,:,i);
    d(:,i)=v;
end
clear d_pp h

%[coeff,score,latent]=pca(zscore(d));
%[coeff,score,latent]=pca(d);
%[coeff,score]=princomp(zscore(d)); 
[cf,P]=princomp(d); %(:,4:13));
%--------------------------------------------------------------------------
%[fc,~,~,~,F]=factoran(d,nf,'rotate','varimax','scores','wls','maxit',5000);

% extraction of factor curves
m=max(F);

 for i=1:nf
    F(:,i)=F(:,i)/m(i);
end

 %C=d(:,4:13)'*F/(F'*F);

 C=d'*F/(F'*F);
 %--------------------------------------------------------------------------
%figure                                                           % figure 3

 a=zeros(is);

 for i=1:nf
    %a(:)=F(:,i);

 end
   for i=(nf+1):2*nf
    %subplot(2,nf,i);
    %plot(C(:,i-nf),'o-');
    %grid on
    %set(gca,'XLim',[0,11],'YLim',[0,35]);
    %ts=['FACTOR CURVE ',int2str(i-2)];
    %title(ts,'FontSize',12);
   end
 %--------------------------------------------------------------------------

 end
   end

When I try to run it I get the error: Exception: java.lang.NumberFormatException: For input string: "untitled.fig" Exception in thread "main" java.lang.NullPointerException at getmagic1.main(getmagic1.java:36)

Can you help me to adapt the code so I can run the file? Thanks a lot!
