Yes thanks. The programm is running now. But I have a new question :D
I have different velocitys and want to combine them in a calibraton curve.
The flowtank flows in Hz and I need a graph which shows the Hz in m/s
I took pictures from 0 to 45 Hz and also did all the stuff you showed in the video... Now I have the Histogram, the Velocity magnitude and the Scatter Plot.
But how can I combine them to one graph that shows on the x-axis m/s and on the y-axis Hz?
You are welcome. But what was the issue?
If you have double images for different RPMs of your flow tank, then you should analyse each double image and export all data to the Matlab environment. Then you can calculate the average velocity and the standard deviation of each double image. And then you can plot this data using Matlabs errorbar(x,y,err) function, where x is RPM in Hz, y is mean velocity in m/s and err is the standard deviation in m/s.
Then you probably also want to have a look at Matlabs 'polyfit' function.
I can combine with this also more than one Pivlab session? And if I do this, and afterwards click on one of the files in the workspace, there are almost no informations in the excel table which opens than.

'File -> Save -> All results to Matlab workspace', or any of all the other options in this menu.
You will have to find out about basic Matlab functionality yourself, I am sure someone bin your lab can help you to work with Matlab!
If cells are empty, it means that you didn't calculate that value in PIVlab.
