I have the following problem:
I have a matrix with 20 columns and over 200'000 rows. somewhere in this matrix there seems to be some strange datas which I would like to delete. If I am looking for the rownumbers where the value is higher than a specific value, lets say I am looking for all the values in the first row that are larger than 1500
If I do this:
I get a logical array, but what I am looking for is the exact row number, what do I need to do?
