I know several variants of this issue have been discussed elsewhere, but I am still unable to solve the problem. Please help.
I have created a function as part of a larger gui, but I am unable to store three data variables (AveX, AveY, AveZ) for later use by guidata(hObject, handles). What am I doing wrong?
Here is my function:
%call all checkbox values
for i = 1:30
checkboxes=get(handles.(sprintf('checkboxAv%d',i)),'value')
Checkboxes(i,1)=checkboxes(1,1);
end
plotdata=handles.plotdata;
[row,col] = find(Checkboxes==1)
num=length(plotdata{1,1}(:,1));
DataY = zeros(num,length(row));%zero matrix
%Average y data
for k=1:length(row)
DataY(:,k)=plotdata{row(k,1),col(k,1)}(:,4);
end
[m,n] = size(DataY)
if (n==1)
AveY=DataY'
elseif (n>1)
AveY=mean(DataY');
end
AveY=AveY';
%Average X data
for kk=1:length(row)
DataX(:,kk)=plotdata{row(kk,1),col(kk,1)}(:,1);
end
test=DataX(:,1);
comp=any(bsxfun(@minus,DataX,test),1)
S = sum(comp)
if (S > 0)
h=msgbox(['Note! Wavelength index for the selected samples are not identical.'])
end
[c,r] = size(DataY)
if (r==1)
AveX=DataX'
elseif (r>1)
AveX=mean(DataX');
end
AveX=AveX';
%Average Z data
for kkk=1:length(row)
DataZ(:,kkk)=plotdata{row(kkk,1),col(kkk,1)}(:,5);
end
[m,n] = size(DataZ)
if (n==1)
AveZ=DataZ'
elseif (n>1)
AveZ=mean(DataZ');
end
AveZ=AveZ';
handles.Aveheader=Aveheader
handles.AveX=AveX;
handles.AveY=AveY;
handles.AveZ=AveZ;
guidata(hObject, handles);
And here is the error message:
Undefined function or variable 'hObject'.
Error in CDanalyzer>AveragePlotFcn (line 5276)

Error in CDanalyzer>checkboxAv1_Callback (line 5076)

You currently have
function AveragePlotFcn(handles)
and call it with
AveragePlotFcn(handles)
Change that to
function AveragePlotFcn(hObject, handles)
and call it with
AveragePlotFcn(hObject, handles)
