Accesing vector data in for loop

I want to access the vector data from several variables in a for loop. I have managed to build the string to load the filename and variables, but the actual data is not accessed.

this is the code:

vars={var1,var2,var3,var4};
for ii=1:length(vars)
    file=dir(fullfile(maindirectory,'mydata.mat'));
    filename=file.name
    fullfilename=strcat(maindirectory,'\',filename);%builds the string
    Data=load(fullfilename,vars{ii});
end

it all falls apart at Data.

The code just loads the struct with fields (var1: [99x1 double]), but not the actual data.

This is very confusing: it is not clear why you call dir when you already know the exact filename:

    file=dir(fullfile(maindirectory,'mydata.mat'));
    filename=file.name
    fullfilename=strcat(maindirectory,'\',filename);%builds the string

Perhaps you just meant to do this:

fullfilename = fullfile(maindirectory,'mydata.mat');

This is expected. Read the documentation on the output of load() applied to a mat file.
