Data File for Production Optimization Problem with MATLAB

Hello everyone, i am working on an optimization algorithm to determine best order line set-up, i have created a data file with columns that have my orders,i am looking to check If the number of orders is not zero from the data file i created and if at least one vessel is not busy in my code, i am looking for a code similar to;

Order >= 1 and Vessel > 0

My question is how do i check conditions from my data file?

Thank you.
