Error using *
Inner matrix dimensions must agree.
Error in extkflid (line 64)
X = X+ K*Y-(H_Lidar*X)

I think that your issue is with K*Y. As best I can tell, K is 3x3, while Y is 2x2, so it is not possible to do matrix multiplication with two arrays of these sizes.

for obtaining sensor fusion thanks to extended kalman filter

Yeah, I am unfamiliar with what that means.
Again, my suggestion is to go back and double check that the math and matrix sizes are what they should be based on hand calculations. If everything does compare with hand calculations, then I would suggest backing it out a bit further, and checking the original math.
