How to remove many NAN rows

2 views (last 30 days)
Hello. I´m new to Matlab and I can´t solve the next syntax problem. That is: I have 4 files (.dat). Each one contents a variable number of rows but all of them have 6 columns. What I want is removing 21st rows of each document (which are NAN, by the way) and join them into one file. Can you help me?
Thanks in advance

Hope the below example helps.
Let the matrix A=[1 2 3;4 5 6;NaN,NaN,NaN].If you want to remove the 3rd row of this matrix, you could use the following command
In order to concatenate the matrices vertically, 'vertcat' command can be used.
Please refer the below documentation on vertcat:

Thanks a lot Gayatri.Vertcat command successfully solves the concatenate's problem. Im relation to removing rows. Could I write A(1:21,:)=[]; in order to delete a range of rows(from 1 to 21)?
