Calculate the error, square it and calculate the mean!
mean( ( a - b ).^2 );

How can I interpolate values ??
I'll explain my situation to you.
I have two arrays.
1.The first array comes from a data acquisition performed through Kinect which has a higher acquisition frequency, in fact the size of this array is 1054x1.
2.The second array comes from a data acquisition performed through an Intel RealSense camera that has a lower acquisition frequency, in fact the size of this array is 601x1.
How can I solve the problem and then proceed to the calculation of the mean square error??

doc interp1
should allow you to resample the 601 up to 1054 (or the 1054 down to 601 if you prefer) and then you can compare per-point, bearing in mind that you are no longer comparing raw data.
