How to count average number of occurance of data and Nan from text file.

1 view (last 30 days)
Dear all,
I'm new to Matlab
I have a text data file like :
# "Frame" "CenterofMass"
0 [5.35542667 7.49759667 6.42651167]
1 [5.36150333 7.49310833 6.44564167]
2 Nan
3 Nan
4 Nan
5 [42.3471765 12.4554735 12.32290767]
6 [22.016623 13.46475567 21.90701423]
7 [32.80792167 13.49493133 21.81519458]
8 Nan
9 [22.05034433 13.24664267 32.74229167]
I wanted to count average occurance of data(some numbers) like: (2+3+1)"sum of data row"/3 '''occurance of data row 3 times' will give average =2
same for Nan : (3+1)/2=2 .
How to do that in matlab.
Any help will be appriciated.
thank you in advance

You can use xlsread function if you have the data in the form of excel or csv.
Let us take a as the variable holding data.
[m n] = size(a);
num_rows_NaN = 0;
num_rows_number = 0;
for i = 1:m
if (sum(isnan(a(i,:)))) == 0
num_rows_NaN = num_rows_NaN + 1;
else
num_rows_number = num_rows_number + 1;
end
end
