Hello all,
I am trying to get the data from a structure but I the problem I am facing is that I am not able to call the Structure though a variable which cointains the structure name. When I am writng the name of the structure specifically then its fine but not otherwise. Can anyone be able to help.
clear all
name='Test_4';
load(name);
Nr_Variabel=length(name.Y);
for k=1:Nr_Variabel
Tem=name.Y(1,k).Data;
Variabel_name=name.Y(1,k).Name;
plot(Tem);
xlabel(Variabel_name);
end

I recommend that you call LOAD with an output argument.
data = load('mymatfile.mat');
Now you can access, for example, the variable named x that was stored in mymatfile.mat as:
data.x
This avoids a problem where your MAT-file contains a variable with the same name as a function [often ALPHA] -- this is known as "poofing" on the MATLAB newsgroup and can be difficult to diagnose.

I'm not really sure I understand the question, but if you mean that a field name is assigned to a variable you can do e.g.
fieldName = 'Data';
result = someStruct.( fieldName );
to access a field using a dynamic string from a variable rather than a hard-coded name.
