I am having some trouble generalizing this logical method. Specifically, I am reading in a .csv file and trying to delete "Rows" that have even numbers:
Dataset=importdata('020513_No11_WithHeaders.csv'); FinalDataSet=Dataset.data; FinalDataSet2=Dataset.data; Row=Dataset.data(:,5); tf=bitget(abs(Row),1)~=0; FinalDataSet2(tf)=[];
However, "FinalDataSet2" is originally sized as 81539x6. When I delete the "tf" values, it turns into a variable that is sized as 1x448465.
Can anyone suggest what I am doing incorrectly here? Thanks!
