Getting average of sections of a single row of data

Hi everyone,
I have a single row of data and I am trying to get the mean of a number of different ranges within it i.e t average of the data within the ranges (1:20), (103:130), (229:259), (351:386), (482:512), (612:641). This is my attempt:
Average=mean(Seg1.P_wave(1:20,103:130,229:259,351:386,482:512,612:641));
However, this returns an error stating that the index exceeds the matrix dimensions even though the matrix contains 747 elements. Does anyone know what I am doing wrong?
Thanks

m1=mean(Seg1.P_wave(1:20));
m2=mean(Seg1.P_wave(103:130));
m3=mean(Seg1.P_wave(229:259));
m4=mean(Seg1.P_wave(351:386));
m5=mean(Seg1.P_wave (482:512));
m6=mean(Seg1.P_wave (612:641));
out=[m1 m2 m3 m4 m5 m6]
%or you want
mean(Seg1.P_wave([1:20,103:130,229:259,351:386,482:512,612:641]));
