Hello,
If I have block matrices A,B,C and D all of which are non singular would this relationship hold; my main concern is preserving order of matrix multiplication:
if ADB=C
then AD=B^-1C
D=B^-1CA^-1
D^-1 = (BC^-1A)
Also is it okay to assume the inverse of a block matrix is equal to a matrix that contains as its elements the inverse of each individual block?
Thanks for any help
