Hi everyone,
I have dataset which has 2832 rows and 4 columns. In this specific dataset I want to retrieve two rows, for example in the image provided for time instant 1.5 I want to get the two values of number of packets for both cachehits and cachemisses and further to the retrieved values I want to implement the formula of Hitratio = (Cachehits)/(CacheHits+CacheMisses) *100 and get the value of hit ratio.

I hope the dataset is in the form of a table. So your table is going to be of size 2832x4.
idx = T.Time==1.5 ;
T1 = T(idx,:) ;
T1.(1)
T1.Node
T1.Type
You can access your required from T1.

Thanks, that works fine. I just have one more question. In the code above why have you declared T1. (1)? Can you please explain? Thank you so much.

Read about table. If you want to access the first column, either you can use T.Time or T.(1). 1 stands for first column.
