How to Execute loop continuously based on vector elements

I have two vectors >> V=1:12; >> L=[ 3 5 8 10] starting from last element of vector L

for i=1:12 if L==10 V(i)=V(i+2)-10*V(i) .... .. next if L==8 do stuff .. .. if L==5 .. .. if L==3 .. ... .. end how could i do this for all elements of L starting last to first in loop fashion..

As per my understanding you want to write a code such that a for loop for array ‘v’ goes in forward direction while another array L goes in the reverse direction to do some functions for a particular L, the code below demonstrates it.

V = 1:12;
L = [3 5 8 10];
j = length(L)
for i = V
    
    switch j
        case 1
            disp('do something 1')
        case 2
            disp('do something 2')
            
    end
    j = j-1;
end
