Unsing string for indexing though structures

1 view (last 30 days)
Hey, I would like to create a while loop with which I can read mat files one after the other and evaluate them automatically without writing a separate program for each mat file. Loading the mat files works using the loop, but unfortunately I can't access the structures with a variable s2.
Does someone have a solution for it?
i = 108;
% A = ((0.1255)/2)^2*pi;
% ml_in_m3 = 1e-6;
while i <= 108
pfad = '...';
s = strcat(pfad,'Test3_',string(i),'.mat');
s2 = strcat('Test3_',string(i));
load(s);
figure(2)
plot(s2.X.Data,s2.Y(8).Data)
t = s2.X.Data;
y = s2.Y(8).Data;
x = 0:0.001:s2.X.Data(end);
y=interp1(t,y,x,'spline');
i = i+1;
end
%the error that occur is: Unrecognized method, property, or field 'X' for class 'string'.

yeah, only the name of the file and the values of the variables are changing
