Expected one output from a curly brace or dot indexing expression, but there were 2 results.

Hi.I working with a code to manipulate some data and here are the lines which gives error

S12(m).x2(n)=S2(tn4).x(ts4) % line 104
S12(m).dx2(n)=S2(tn4).dx(ts4) % line 105
S12(m).z(n)=S2(tn4).y(ts4) % line 106

The error is,

Expected one output from a curly brace or dot indexing expression, but there were 2 results.

Error in data_man (line 104) S12(m).x2(n)=S2(tn4).x(ts4)

How can I fix this error?

Could you attach the missing datas as a .mat file?

[madhan ravi]

I can't see your file.

Here is the data file, I renamed the Newtracks as S2 in the following code. The error is in line 104

S12(m).x2(n)=S2(tn4).x(ts4) % line 104
S12(m).dx2(n)=S2(tn4).dx(ts4) % line 105
S12(m).z(n)=S2(tn4).y(ts4) % line 106

In general you are not allow to assign multi-level structures with non-scalar indexing in one shot, you need to do in 2 steps.

%  S12(m).x2(n)=S2(tn4).x(ts4)
x2 = {S12(m).x2};
x = {S2(tn4).x};
for k=1:length(x2)
    x2{k}(n) = x{k}(ts4);
end
[S12(m).x2] = deal(x2{:});

I have tried your suggestion and it results in follwoing error:

Reference to non-existent field 'x2'.

I am unable to resolve the error since, x2 is already defined.

This approach worked for:

names = {'a' 'b' 'c'};

dStruct = repmat(struct('name',''),size(names));

[dStruct.name] = deal(names{:});

Also works without "deal":

[dStruct.name] = names{:};

In other threads, there are discussions regarding "deal" being unnecessary in later releases.

Thank you Bruno Luong.
