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
%--------------------------------------------------------------------------
% PRINCIPAL COMPONENT ANALYSIS - for variants and details cf Matlab help
%[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);
[fc,~,~,~,F]=factoran(d,nf,'rotate','varimax','scores','wls','maxit',7000);
% rotate - for details cf Matlab help
% none
% equamax
% orthomax
% parsimax
% pattern
% procrustes
% promax
% quartimax
% varimax
% scores - for details cf Matlab help
% wls or Bartlett
% regression or Thomson
%--------------------------------------------------------------------------
%--------------------------------------------------------------------------
% 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!
