[[1 0 1] [1 1 0]] [[3 0 0 3] [2 2 1 3] [1 3 1 1]] [[4. 3. 1. 4.] [5. 2. 1. 6.]]
乘以
=
c11= a11*b11 + a12*b21 + a13*b31 == 1*3 + 0*2 +1*1 = 4
c12= a11*b12+ a12*b22+ a13*b32 == 1*0 + 0*2 + 1*3= 3
c13=a11*b13+ a12*b23+a13*b33
c14=a11*b14+ a12*b24+a13*b34
c21=a21*b11 + a22*b21 + a23*b31
c22= a21*b12+ a22*b22+ a23*b32
c23=a21*b13+ a22*b23+a23*b33
c24=a21*b14+ a22*b24+a23*b34
So:
C=
[[4. 3. 1. 4.] [5. 2. 1. 6.]]
