My data is not numeric and a similar command results in an error. How can I count the number of elements that has D_S='0-30' & the damage rate is 'No Damage' ? My table is attached below

Convert those variables to categorical which is what they are, really, not string. Then, internally to Matlab, they are numerical but the interface is still human-readable.)
