If
a11=[0.1 0.4 0.5 0.6];
a12=[0.5 0.04 0.045 0.0006];
a13 = [0.0055 0.4 0.0445 0.10006];
a21 = [0.155 0.1044 0.045 0.1006];
a22 = [0.55 0.104 0.2045 0.06];
a23 = [0.55 0.0044 0.45 0.006];
a31= [0.155 0.1044 0.045 0.1006];
a32=[0.1 0.9 0.005 0.006];
a33=[0.001 0.002 0.002 0.105];
Then, how can i compute inverse of matrix A=[a11,a12,a13;a21,a22,a23;a31,a32,a33]?

The inverse of a 3-d matrix has no definition in mathematics that I know of. So in order to do what you want, you first need to define that operation. Then you need to write code for that purpose.

There is misunderstanding between the question and the provided example, according the question, Jhon's answer is correct, three dimensional matrices are out of scope, but the example you gave is a 3 by 12 matrix, generally for non square matrix, the inverse is generalized inverse pinv(A).
