I have a large table with data on traffic times and modes. A sample is given below:
Now I would like to remove all rows with a zero. This would be easy to perform on a matrix with something like this:
rows_to_remove = any(data==0, 2);
data(rows_to_remove,:) = [];
However, when I load this table as a matrix, the text data on the travel mode is converted into a numerical value that has no meaning.
How do I remove all rows with a zero while keeping the text in the 5th and 7th column?

Are those two numbers separated by a comma a string? Or is that like some European countries that use a comma instead of a decimal point so they are really numbers, not strings? Can you attach your data file?
