15 Feb 2011 scatplot Scatter plot with color indicating data density. Author: alex sanchez Jin, Hongxiao

%this works fine for simple show
function hh=scatterC(varargin,n,method)
if nargin<2
    n = 100; %bins
    method='p'%pcolor
end
if nargin<3
    method='p'
end

[N C]=hist3(varargin,[n,n]);
N(find(N==0))=NaN;
[X Y]=meshgrid(C{1},C{2});
switch method
    case 'p'
        pcolor(X,Y,N);shading flat;
    case 'c' %contourf
        contourf(X,Y,N,'EdgeColor','None');
end

11 Mar 2010 winsinc Applies a windowed sinc filter. Author: alex sanchez Tom

This is a very useful function. Thank you very much.

One comment: wkeep is in the wavelet toolbox. I believe using

xf = conv(x,h,'same');

gives the same results as

xf = conv(x,h);
xf = wkeep(xf,N);
12 Jan 2010 plamovie Plays a matlab movie, with the option of using a slider Author: alex sanchez Campbell, Rob

I wasn't able to get this to work on 2009b. I had to modify line 120 to update it to current standards. I now get improper matrix reference at line 153. Unclear why this should be the case.
