Hi,
I understand what error says but I don't know how to improve my function. I am not sure what exactly is seen as cell and how to achieve my goal. I loaded file to be read.
*Error using subsindex Function 'subsindex' is not defined for values of class 'cell'.
Error in EEGmeans (line 36) means(i) = mean(alldata(n,:));*
function [ means ] = EEGmeans( ) %EEGmeans loads the .mat file with EEG signal and calculates means for
%electrode and trials determined by user
%loading .mat file
load('eeg_data.mat'); %user determines number of elecrode and trials
for h=1:64 disp([num2str(h), ' - ', data_org.label{h}]) end eprompt = 'Type number of electrode. You can see displayed numbers and labels in your command window.'; tprompt = 'Type numbers of trials (1-61) in form of a vector [t1, t2, t3, ...].'; edlg_title = 'Electrode'; tdlg_title = 'Trials'; num_lines = 1; defe = {'1'}; deft = {'[1, 2, 3]'}; electrode = str2double((inputdlg(eprompt,edlg_title,num_lines,defe))); trials = (inputdlg(tprompt,tdlg_title,num_lines,deft)); alldata = zeros(61,160); %getting data for trials for selected electrode
for g = 1 : 61 alldata(g,:)=data_org.trial{g}(electrode,:); end %calculating means
means = zeros(1, length(trials)); for i = 1 : length(trials) n = trials(i); means(i) = mean(alldata(n,:)); end %displaying results
msgbox('Operation Completed. Arithmetic means for given electrode and trials are as follows: ', 'Success','custom', means); end
