given a Matrix(n,m) i need to delete certain rows (or columns) defined by a vector

example:
M=magic(4)

M=[16 2 3 13
5 11 10 8
9 7 6 12
4 14 15 1]

F=[1 0 0 1]; %delete column 1 and 4

-> should result in
M=[2 3
11 10
7 6
14 15]

i wrote a function:

function t=TrimMatrix(M,V)

j=0;
if size(V,1)==1
for i=1:size(V,2)
if V(1,i)==1
M(:,i-j)=[];
j=j+1;
end
end
else
for i=1:size(V,1)
if V(i,1)==1
M(i-j,:)=[];
j=j+1;
end
end
end
t=M;


do you have any better solutions? is there any way not to use iterations?
