Here is one way:
P = @(x,c,w) exp(-w*(x-c).^2); % Function to calculate peaks
W = 2; % Width (constant here, can vary as a vector if you like)
C = 5:5:15; % Peak centers
x = linspace(0,20,250); % Define ‘x’ vector
pks = zeros(size(x)); % Preallocate ‘pks’
for k1 = 1:length(C) % Loop through ‘C’ (centers) vector
pks = pks + P(x,C(k1),W);
end
figure(1) % Plot
plot(x,pks)
grid
produces:
