Create submatrix from large array based on string in column

Hello,

I have a very large data set imported from a .csv file that contains both numbers and strings. One of the columns (column 9) contains different pollutant names. I ultimately want to make a file that contains all the rows related to ozone. I have done this with numbers from excel documents, but the same thought process doesn't seem to be working for me here.

Any thoughts?

Thanks,

filteredcellarray = yourcellarray(strcmp(yourcellarray(:, 9), 'Ozone'), :)
