You aren't going to get very good smoothing with such a small amount of data, but here is one possibility (of many):
data = [ ...
1 NaN
2 1.356390367
3 1.295994741
4 1.50041999
5 2.790612162
6 4.62246207
7 6.134079946
8 6.818989019
9 7.953940954
10 7.2993
11 10.4519388
12 12.4768
13 10.6323
14 NaN
15 11.94706861
16 6.180212227
17 7.622561145
18 6.229011638
19 4.09315833
20 2.495924367
21 2.213217555
22 2.735480781
23 2.071762287

];
plot(data(:,1), data(:,2))
hold on
sm_data = smoothdata(data(:,2), 'sgolay'); % save the smoothed data
plot(data(:,1), sm_data)
grid on
legend('original data', 'smoothed data')

You are welcome.
If you want to save the smoothed values, just assign the output of smoothdata() to a variable.
I've edited my answer to reflect this.
