Hello,

Is it possible to create a structure in a for loop

field={'name1','name2'}

for i=1:2

structure.(field{i})=value

end

Output:

structure.name1=value

structure.name2=value

Thanks

Jinang

Please, use the code format.

What are you having issues with? This will work just fine.

hey,

a={'see','why'}

KPI={'L','L2','L3'}

struc.a{1}.KPI{1}=5

Output

"struc =

struct with fields:

a: {[1×1 struct]}"

I would expect

struct.see.L=5

Use the syntax shown in the MATLAB documentation:

>> a = {'see','why'};
>> KPI = {'L','L2','L3'};
>> S.(a{1}).(KPI{1}) = 5;
>> S.see.L
ans =  5

hello Stephen,

I am trying to assing value to each field name, however this is not possible since assign value to 1st field name limits the structure. Is there a way to assign value to individual fields?

a = {'see','why'};

KPI = {'L','L2','L3'};

S.(a{1})=6;

S.(a{1}).(KPI{1}) = 5;

Output

S.see=6;

S.see.L=5;

That is not possible. A field contains one array, i.e. the field can contain either a numeric array or another structure array, but it cannot simultaneously contain both.
