Linear interpolation of matrix

I have a set of data point which are represented in matrices. So basically I have one input and I get a matrix as an output. If i have two inputs which means two output matrices, how can I use linear interpolation to find the output matrix for a random input? Looking forward to your help.

>> M1 = [1,1,1;2,2,2];
>> M2 = [3,4,5;6,7,8];
>> P1 = 0;
>> P2 = 1;
>> Pq = 0.5; % your random point
>> V = [reshape(M1,1,[]);reshape(M2,1,[])];
>> Vq = interp1([P1;P2],V,Pq);
>> reshape(Vq,size(M1))
ans =
   2.0000   2.5000   3.0000
   4.0000   4.5000   5.0000
