MATLAB: Calculating difference of unequal vectors

unequal vectors

I have a four vectors as shown below where Exp_temp and Exp_time are the experimental values and Num_temp and Num_time are the numerical results. I want to calculate the difference between experimental and numerical values.The length of the vectors and sample interval are unequal. How to calculate the difference.
Num_temp = [5; 6; 8; 5; 4; 3; 7; 3]; Num_time = [1; 2; 3; 4; 5; 6; 7; 8];
Exp_temp = [2; 3; 1; 2; 4; 7]; Exp_time = [1; 2; 4; 6; 7; 8];
