If you want to consider your array to be just a set, i.e. to forget the
row/column indices, then Flatten is your function :

In[1]:= Flatten[{{1115.67, 1169.42, 1243.33, 1270.6}, {1169.39, 1220.86,
1261.8, 
   1173.26}, {1133.4, 1173.71, 1168.89, 1174.48}}]

Out[1]= {1115.67, 1169.42, 1243.33, 1270.6, 1169.39, 1220.86, 1261.8,
1173.26, \
1133.4, 1173.71, 1168.89, 1174.48}
