Find quasi-periodic peak locations from noisy photon count data

 I am trying to find the method of locating the gaussian peaks from the photon count data. x axis is the number of photons for each spot and y axis is the counted spots.


I used findpeaks function to find peaks. The solid line is created by sgolayfilt.
 
 
hgcs = sgolayfilt(hgc, 10, 41);
plot(hgc); hold on;plot(hgcs)
findpeaks(hgc, 'MinPeakDistance', 20)
The peaks that I want to recover are located about 40, 80, 120, and 160.
 
Question1: Are there any functions or algorithms that can determine the number of peaks and the locations?
 
Question2: After 160, there are small features. Some of them may be still peaks following the first four peaks. At least, we know that the locations of peaks are quasi-periodic. Could we also find more peaks?

I gave up on estimating the width parameter, and just went for the amplitude and location with a uniform width.
Try This:
 
D = load('hgc.mat');
hgc = D.hgc;
x = linspace(0, numel(hgc), numel(hgc));

hgcs = sgolayfilt(hgc, 10, 41);

figure
plot(x,hgc)
hold on
plot(x,hgcs)
hold off
grid

[pks,locs,w] = findpeaks(hgc, 'MinPeakDistance', 20, 'MinPeakProminence',5);

gausfcn = @(b,x) b(1).*exp(-(x-b(2)).^2 * 0.05);

for k = 1:numel(locs)

What are some good alternatives to Simulink?

Get MATLAB projects with source code for your learning and research. SIMULINK is a visual programing environment specially for time transient simulations and ordinary differential equations. Depending on what you need there are plenty of Free, Libre and Open Source Software (FLOSS) available: Modelica language is the most viable alternative and in my opinion it is also a superior option to MathWorks SIMULINK. There are open source implementations  OpenModelica  and  JModelica . One of the main advantages with Modelica that you can code a multidimensional ordinary differential equation with algebraic discrete non-causal equations. With OpenModelica you may create a non-causal model r...

USING MACHINE LEARNING CLASSIFICATION ALGORITHMS FOR DETECTING SPAM AND NON-SPAM EMAILS

    ABSTRACT We know the increasing volume of unwanted volume of emails as spam. As per statistical analysis 40% of all messages are spam which about 15.4 billion email for every day and that cost web clients about $355 million every year. Spammers to use a few dubious techniques to defeat the filtering strategies like utilizing irregular sender addresses or potentially add irregular characters to the start or the finish of the message subject line. A particular calculation is at that point used to take in the order rules from these email messages. Machine learning has been contemplated and there are loads of calculations can be used in email filtering. To classify these mails as spam and non-spam mails implementation of machine learning algorithm  such as KNN, SVM, Bayesian classification  and ANN  to develop better filtering tool.   Contents ABSTRACT 2 1. INTRODUCTION 4 1.1 Objective : 5 2. Literature Review 5 2.1. Existing Machine learning techniqu...
