No, I've never used simulink.
25 Jan 2010 nonduplicate Makes all values of input array distinct - used to get interp1 to work when x data has duplicates. Author: Nathan Tomlin

Orlando - unique returns a smaller array, [1,1,2] becomes [1,2]. While nonduplicate keeps the same number of values, but slightly shifts them so [1,1,2] becomes [1,1+eps,2]. The idea was to get interp1 to work by changing the values as little as possible.

'Anon' - Great point, this code is not a good idea if there is a lot of noise or large outliers in the y data. I hadn't heard of consolidator - I will check it out.
19 Jun 2009 Thresholding Tool Interactively select intensity level for image thresholding. Author: Robert Bemis

I apologize for cluttering the comments - didn't read carefully (and wish I could edit previous posts...). Like Benjamin said, it doesn't work if you input an RGB image. Just add:

if ndims(im) == 3
im = rgb2gray(im);
end
thresh_tool(im)

21 Aug 2012 DAQmx examples Examples of talking to a National Instruments (NI) DAQ card without the data acquisition toolbox. Author: Nathan Tomlin Armstrong, Alan

I've tried to use your code but every time I try to load the library I get:

Warning: Warnings messages were produced while parsing. Check the functions you intend to use for correctness. Warning text can be
viewed using:
[notfound,warnings]=loadlibrary(...)
> In loadlibrary at 344
In TestDAQCard_1 at 11
Error using loadlibrary (line 419)
There was an error loading the library "C:\Documents and Settings\Administrator\My Documents\PhD\MATLAB\Experiment_2\nicaiu.dll"
A dynamic link library (DLL) initialization routine failed.

Error in TestDAQCard_1 (line 11)
loadlibrary('nicaiu.dll', 'NIDAQmx.h', 'mfilename', 'b') % The lib and h files are both in the matlab path so no need for the
above line(s)

Caused by:
Error using loaddefinedlibrary
A dynamic link library (DLL) initialization routine failed.

I use 'loadlibrary('nicaiu.dll','NIDAQmx.h', 'mfilename', 'b')' since I've added niaiu.dll and NIDAQmx.h to my matlab folder.

can you help?

thanks

Hello, I have to acquire some analog samples over 30 seconds (1 sample every 0.01s). How can I do using a for loop in Matlab ?
