% create dummy variable voor test sinus met noise of alleen noise	%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


% Create a 15-by-250-by-18 array of random numbers.
X = randn([1000,250,18]);
x = -pi:0.1:pi; % met 0.1 lengte y is 63
y = sin(x) *15; % *15 zodat het te onderscheiden is ook visueel van X (max(X) rond 3 a 4)

% add sinus in de eerste 300 signalen
X_sin = X;

for i = 1:100
    X_sin(i,1:63,1) = X_sin(i,1:63,1) + y; % eerste epoch; eerste kanaal
end

for i = 101:200
    X_sin(i,1:63,2) = X_sin(i,1:63,2) + y; % 2e epoch; 2e kanaal
end

for i = 201:300
    X_sin(i,1:63,3) = X_sin(i,1:63,3) + y; % 3e epoch; 3e kanaal
end

% X_sin(4,1:63,4) = X_sin(4,1:63,4) + y; % 4e epoch; 4e kanaal
% X_sin(5,1:63,4) = X_sin(5,1:63,5) + y; % 5e epoch; 5e kanaal

% export X_sin naar PyCharm als input variabele

% create output variabele
A1 = ones(300,1);
A2 = zeros(700,1);
Y_sin = [A1; A2]; % onder elkaar
% export to python
