Structure Assignment to Non-Structure Object Error

I'm trying to reassign structs from a loaded .mat file to a new .mat file.

In a loop I have the new struct I would like to load the information into equating the struct from the older .mat file

The code looks something like this

files = dir('*.mat')

for i= 1:numel(files)
fileName=files(i).name

load (fileName)

newstruct(1).struct = oldstruct.data

save (newstruct)

end

any ideas why I am getting this error?

What error? Please post the error messages.

I get a similar error while plotting

i_fig = i_fig +1 ;
f_h(i_fig) = figure ;
[axh, axh1, axh2] = plotyy( labeledTerms, PGDerror(labeledTerms),...
    labeledTerms, iterV(labeledTerms),...
    @semilogy, @plot );
set( axh, 'fontsize', 15, 'xtick', labeledTerms, 'ytickmode', 'auto' )
axh(1).YLabel.String = 'PGD error indicator';
axh(1).XLabel.String = 'Modes'; 
axh(2).YLabel.String = 'Iterations per mode';
axh(2).YTick         = 1:max(iterV);
axh(1).XTick         = 0:10:m+1;

Error occurs on the line

axh(1).YLabel.String = 'PGD error indicator';

Kiran Sagar: which MATLAB release are you using? plotyy() suggests you might be using R2014a or earlier, which does not allow field reference notation for setting properties. If you are using R2014a or earlier, you would need to change those assignments into set() calls.

 if(C(i)<=(p/(1-p*mod(r,round(1/p)))))
                    countCHs=countCHs+1;
                    S(i).type=1;
                    C(cluster).type=S(i).type;
                    C(cluster).xd=S(i).xd;
                    C(cluster).yd=S(i).yd;
                    C(cluster).id=i;
                    C(cluster).E=S(i).E;
                    dis(cluster)=sqrt((S(n+1).xd-S(i).xd)^2+(S(n+1).yd-S(i).yd)^2);
                    cluster=cluster+1;
                    subplot(2,2,ss), plot(S(i).xd,S(i).yd,'r*');
                    X=[S(i).xd,S(n+1).xd]; Y=[S(i).yd,S(n+1).yd];
                    for j=1:1:n
                        if distance(i,j)<=R && j~=i && S(j).type==0
                            S(j).type=3;
                        end
                    end

I am also facing same problem in this code

[Walter Roberson]

Sunil Kumar Patel:

In the line

if(C(i)<=(p/(1-p*mod(r,round(1/p)))))

the comparison involving C(i) can only work if C(i) is numeric.

Then a few lines later you use

                    C(cluster).type=S(i).type;

which tries to use C as a structure.

The first argument to save() should be a filename. You are passing a structure instead.
