EURUSD=X.csv

Hello. For some reason the number of inputs does not match the net number of inputs. Inputs is a 13x80 array and the labels are a 1x13 so I'm not too sure why this isn't working. Any help would be greatly apprectiated.

data =readtable('EURUSD=X.csv');
[m,n] = size(data);
k = floor(m/20)*20; % gives me exact number of rows of data for 20 days period
data = data(1:k,:); % removes extra unwanted trailing data
Open = data(:,2);
High= data(:,3);
Low = data(:,4);
Close = data(:,5);
G = floor((0:height(data)-1)/20).' + 1;
DataE20 = splitapply(@(Date,Open,High,Low,Close,AdjClose,Volume) {[Open,High,Low,Close].'}, data, G);
inputs = zeros(length(DataE20),80);
%makes each 4x20 arry in DataE20 into a 1x80 array 
for k = 1: length(DataE20)
    tmp = DataE20{k};
    tmp  = tmp(:);
    inputs(k,:) = tmp;
end
Start = cellfun(@(x)x(1),DataE20);
Finish = cellfun(@(x)x(end),DataE20);
x = length(DataE20)
%Create lables
for y = 1:x
   if Finish(y)>Start(y);
       Labels(y) = 1;
    else
        Labels(y) = 0  ;
    end
end
for layer1 = 1:15
    for layer2 = 1:15
        network = patternnet([layer1 layer2]);
        network.trainParam.showWindow = false;
        trained_net = train(network,inputs',Labels); %network,input,target
        op = trained_net(DataE20);
        conf = confusion(Labels,op);
        if best_conf>conf
            best_conf = conf;
            best_net = trained_net;
        end
    end
end
