Hello everybody,
I have a matrix A and at the 10th column is the direction of my wind (0-360). Now I want to make an area just form 135-315 and erase the lines which are out of the area.
Here is what I made but something must be wrong...
DI = 135<A(:,10) & A(:,10)<315
A(DI,:) = [];
Thanks
Lucas

if you want to delete the rows that are not within your range, it should be,
DI = A(:,10)>135 & A(:,10)<315;
A(~DI,:) = [];
