i have vector with positive values and negative for eg
-0.26476
-0.27643
-0.24648
+0.02679
+0.0546
-0.2000
+0.5545
+....
+.....
i would like to delete all the values until the last negative value
k_2 = find(removing <= 0);
s_u(k_2)=[];
it selectively deletes all the negative values.
and when i use
k_2 = find(removing <= 0);
s_u(1:k_2)=[];
it does nothing
thank you

x = x(find(x < 0, 1, 'last'):end);
