How can i extract empty lines from many vectors and associate the result to a matrix ?

I have a little problem to handle Matlab honestly, I have a huge Excel file but I have to treat it with Matlab to extract just the lines where there are data (tracks) and each track takes an index so treatment is made in the first column of the file called MOS, my file contains three columns and n rows, my code below will explain better what I want to do. My worry is even entering the for loop it still can not read the necessary lines or to the displayed properly.all lines are displayed '0' so I must put the result of each column MOS RXLEV, RXQ in a matrix of 4 columns (MOS RXLEV, RXQ, index) and of course n lines and I still can not display it properly. scripttab: the script generate file testmatlab.xlsx dataext: the extraction code and data handling

PLZZZZZ HELP :(

You forgot to attach the code. The code is required to understand, what you are doing and to suggest a solution.

I recommend to omit the kewl "PLZZZZZ". The majority of the questions using such smart looking phrases cannot be answered due to a lack of information. Therefore a "PLZZZ" discourages me immediately to spend time for reading the question.
