Import .mat files and arrange some data in a matrix

files2import= dir('*.mat');
frac_am= cell(1,length(files2import)); % initiation cell array for each needed value
frac_cbm= cell(1,length(files2import));
cond_El_eff= cell(1,length(files2import));
cond_Ionic_eff= cell(1,length(files2import));
aS_eff= cell(1,length(files2import));
numVal= 5; % need variables from 3D simulation(here: frac_am,frac_cbm,cond_El_eff,cond_Ionic_eff,aS_eff)
for filei=1:length(files2import)
    load(files2import(filei).name);    % load datas from .mat files in workplace
    frac_am{filei}= all_frac_am;       % acquire datas from each test and put them in a cell
    frac_cbm{filei}= all_frac_cbm;
    cond_El_eff{filei}= cond_El_eff_stack;
    cond_Ionic_eff{filei}= cond_Ionic_eff_stack;
    aS_eff{filei}= aS_eff_stack;
    if filei==1 %initiation of matrix containing datas from all tests
        alldataM= zeros(length(files2import),numSamples,numVal);
    end
    alldataM(filei,1,:)= all_frac_am; 
    alldataM(filei,2,:)= all_frac_cbm;
    alldataM(filei,3,:)= cond_El_eff_stack;
    alldataM(filei,4,:)= cond_Ionic_eff_stack;
    alldataM(filei,4,:)= aS_eff_stack;
end

So this is my code but I get always this error: "Cell contents assignment to a non-cell array object." all values are in size 1*numSamples. I need them organized so I can use them in some graphs.

In your code, all_frac_am variable is not defined. Maybe you have its values already available in your matlab workspace?

Yes, they are all datas from a .mat file.

Set Pause on Errors and run again

Answer 2

[Sina Kafshi]

yes, it pauses on "cond_Ionic_eff{filei}= cond_Ionic_eff_stack;" but cond_Ionic_eff_stack is just like other variables of size 1*10
