Dataset comparison with different sample rate and start/stop times

Hello,
I have two devices in my hand. One is the encoder and other one is the IMU. The IMU attached to the encoder and then both are rotated simultaneously. I gather data from both devices with generic timestamps (GMT+3) import into the matlab using 'datenum' and 'xlsread' functions.
Here is the plot I get,
I need the differences in between to measure a mean error where the encoder data is the reference. But two vectors are not in same length due to the different sampling rates of devices. I tried many options; DSP tools , interp1, interpolation etc. Can you help me with this simple problem ?
NOTE: It is not really have be in the MATLAB environment. But I believe MATLAB is capable of doing such things ( Maybe not the easiest solution; easiest solution I prefer)
