How can I convert 2D matrix into a sequence?

I need to convert a matrix into a sequence. I have performed PCA on it and obtained 6 principle components. The PC1 contains almost 51 percent information. PC1 and PC2 contains 99% information. Is there any way that I can use PC1 and PC2 as a sequence in a sequence classifier or generate a sequence from above mentioned matrix. Anyone can give any hint or idea please.
