Hello,
I have taken measurement with a laserscanner (profilometer). It seems that the profilometer was not aligned properly to the object.
How can I rotate the following signal around the midpoint in such a way that it simulates a perfectly aligned laserscanner.
The blue line is my measured signal. The red line is what I want.
Can is use normalization, median, mean, etc...do get the signal I want?

If the red curve and blue curve consist of corresponding point pairs, then you can use absor,

to roto-align them.
[~,~,result]=absor(blue,red);
