I am trying to create a new column that has the average of the 10 data points before and after that time point from an existing column (peak heights). Obviously there will be some difficulty for the first 10 and last 10 rows.

Ran in:
Try this —
T1 = table(randn(20,1))
T1 = 20×1 table
Var1 _________ 0.24004 0.36596 0.63986 -2.6273 -0.5487 -1.7412 -0.40701 0.31528 -0.62188 0.95605 -0.17599 0.83996 0.3583 -0.050693 -0.85835 0.032795
T1.Var2 = movmean(T1.Var1,[10 10])
T1 = 20×2 table
Var1 Var2 _________ _________ 0.24004 -0.32772 0.36596 -0.23041 0.63986 -0.18513 -2.6273 -0.17553 -0.5487 -0.22105 -1.7412 -0.20518 -0.40701 -0.22255 0.31528 -0.18343 -0.62188 -0.13606 0.95605 -0.15936 -0.17599 -0.15936 0.83996 -0.18038 0.3583 -0.21073 -0.050693 -0.26077 -0.85835 -0.11286 0.032795 -0.083805
