Hello, I have something as following: a = Array[aa, {3, 3}]; b = Array[bb, {3, 3}]; c = Array[cc, {3, 3}]; d = Array[dd, {3, 3}]; A = {{a, b}, {c, d}} (* A consists of four blocks *) A // MatrixForm And I want a 6*6 matrix (a list of 6 lists) just as A looks like. For example, the first row should be aa[1,1],aa[1,2],aa[1,3],bb[1,1],bb[1,2],bb[1,3] etc.... How to get it easily? Many thanks. Xun
