first row(MRR...) has date and time second row(RR...) has rain rate data. and the data structure repeated. but sometimes date is given but below that data is missing . so i want to delete that date rows which do not have any data bellow . so I will get the file like

MRR...
RR...
MRR...
RR...
MRR...
RR...
.
..
.
I hope you understand my question. thank you.

Rows 11 and 12 have different values for MMR.

 MRR 180531000500 ...
 MRR 180531000600 ...

respectively, however they are identical otherwise. In this example for two rows, do you want to eliminate row 12?

[pruth]

thank you for your reply. I want to eliminate row number 11, not 12. because row number 12 has data below it. in that file there ample of such rows are present which I want to eliminate. sometimes there are 4 MRR rows are present one below other in this case I want to delete first 3 MRR rows. just like above example is given in question itself.

How about this:

isMRR=cellfun(@(x) strcmp(x(1:3),'MRR'),data);
isRR=cellfun(@(x) strcmp(x(1:2),'RR'),data);
toBeDeleted=isMRR(1:(end-1)) & ~isRR(2:end);
data(toBeDeleted)=[];

perfect !!!
