How to make a structure with numerous(>200) fields with loop?

Hello everyone,

I want to make a structure with fields for each patient, then the cell type(5 by 5) EEG data would be allocated to the fields.

I simply know this way,

S = struct('Pt1',data1,'Pt2',data2,....blablabla)

this makes super long awful code...

I've tried loop like this way but it didn't worked

for i = 1:n

S = struct(strcat('Pt_',num2str(i)),Data(i))

end

please help me :)

You could use CELL2STRUCT:

for which NUM2CELL might als be useful. Or NUM2CELL and then a comma-separated list with STRUCT:

Most likely a loop is not required.

n= 5;
Data = randi([1 10], [5 1])

Data = 5×1

8 2 1 5 8

for i = 1:n
    S.("Pt_"+i) = Data(i);
end
S

S = struct with fields:
    Pt_1: 8
    Pt_2: 2
    Pt_3: 1
    Pt_4: 5
    Pt_5: 8
