Hello, As a part of my project, I want to extract the state space point distribution features from speech signal. I get the scatter plot of reconstructed state space. Then I want to compute number of points in each cell from that scatter plot. Please help me to compute number of points in each cell of that scatter plot.Please assist. Thanks in advance. Rahiba
clear;
clc;
[x,Fs]=wavread('C:\Users\raiba\Desktop\project\database\1\1\3.wav');
Y=get_delay_vector(x,2,1);
plot(Y(:,1),Y(:,2));
set(gca, 'XTick', [-1:0.1:1])
set(gca, 'YTick', [-1:0.1:1])
scatterplot(Y);
set(gca, 'XTick', [-1:0.1:1])
set(gca, 'YTick', [-1:0.1:1])
grid on;
function Z=get_delay_vector(data,embed_dimen,delta)
data_size=size(data);
if data_size(1)<data_size(2)
data=data';
end
data_size=size(data);
Z=zeros(data_size(1),embed_dimen);
for i=1:embed_dimen
Z(:,i)=circshift(data,[-(i-1)*delta,0]);
end
end

The inpolygon function would be my first approach to do what you want. You would have to iterate over all your cells.

There are some 2D histogram functions you could use: http://www.mathworks.com/searchresults/?c[]=entire_site_en&q=hist2
