Actually, as you said your matrices have block structure it would probably be
useful in studying your problem
if you could save the blocks separately in those files, e.g.:
A_blocks{1,1} = … ;
A_blocks{1,2} = … ;
A_blocks{1,3} = … ;
…
b_blocks{1} = … ;
b_blocks{2} = … ;
b_blocks{3} = … ;
…
save example.mat A_blocks b_blocks
