The Strange Case of the Determinant of a Matrix of 1s and -1s

matlab中title中字符串换行的办法：
title(['abc','L Range:',num2str(a),'(nm)','~~',num2str(b),'(cm)','B Range:',num2str(c),'(cm)','~~',num2str(d),'(cm)']);
使用元胞数组便可以了：
title({['abc','L Range:',num2str(a),'(nm)','~~',num2str(b),'(cm)'];['B Range:',num2str(c),'(cm)','~~',num2str(d),'(cm)']});
