Hi all,
I have this code beneath and I am wondering if and how I could put this in a for loop in order to only have a code of about 5 lines or so?
Thanks in advance!
%% 1. Data laden
load('PP1_TOJ.mat');
%% SOA -350ms
responsemin350=Data(Data(:,3)==-350,[3 6]);
xmin350=(responsemin350==80);
soundfirstmin350=sum(xmin350, 'all');
ymin350=(responsemin350==79);
lightfirstmin350=sum(ymin350, 'all');
soundfirstmin350(soundfirstmin350==0)=1;
lightfirstmin350(lightfirstmin350==0)=1;

Try this:
D = load('PP1_TOJ.mat');
Data = D.Data;
V = [-350:100:150 -50:50:50 150:100:350];
for k = 1:numel(V)
responsemin{k,:} = Data(Data(:,3)==V(k),[3 6]);
soundfirstmin{k,:} = sum(responsemin{k}==80, 'all');
lightfirstmin{k,:}=sum(responsemin{k}==79, 'all');
soundfirstmin{k,:}(soundfirstmin{k}==0)=1;
lightfirstmin{k,:}(lightfirstmin{k}==0)=1;
proportionlightfirstmin{k,:}=lightfirstmin{k}/20;
end
The results are each (12x1) cell arrays. The ‘k’ subscripts correspond to the elements of ‘V’.

soundfirst{k,:}=sum(response{k}==80, 'all');
% ^ ^
% not (k)
%and before your loop:
response={};
lightfirst={};
soundfirst={};
