Is there a Matlab function that counts how many rows contain a specific string pattern?

Question

I am working with Matlab R2020b and I am not very familiar with it unfortunately. I have a table containing 3 columns and 200 rows. I want to count all the rows which contain a certain string "j7" in column1. Is there such a function?

Answer 1

Not the most elegant way but I found a solution on another thread:

idx = strfind(table, 'j7');
idx = find(not(cellfun('isempty', idx)));
idx = length(idx) ;
