Working with csv files

I would like to know if there is a way to, when importing data from a csv file, choose only lines or colums where especific words (latitude for example) appear, so that in the end I have a matrix only with what I choose.

Given that csvread/dlmread require numeric data, your best bet might be to read the file into matlab in full, separating by commas, and then matching to the desired string. If you can post a few lines of the file (that contain the target words), we can provide more information.
