I divided two m x n matrixes A and B into several equal i x j matrices using mat2cell, respectively, and then I want to multiply the respective split matrixes and sum them together like
A11, … , A1j , ... Ai1, … , Aij are built from A, and
B11, … , B1j , ..., Bi1, … , Bij , are built from B,
What I want is
C = A11* B11 + … + Aij* Bij
Are there any commands in matlab can do this?
