how delete all the negative values

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);
