I guess you can help me regarding this (quite novice) question. The fact is that I have a 2d array of several thousand rows and 5 columns, and I need to filter all the rows of the original array when the corresponding elements in the first and second column, for a given row, equals to some values (Ex: col 1=2 and col_2=0).
I know how to do that in two lines (first filtering for the first column, and then filtering on the resulting array over the second column). SO I know how to do that but… the question is: can I do the filtering in a single, simple line?
Best regards and thanks,
