MATLAB: Excluding some elements from a Vector

elementvectors

qw=[1:0.4:50]';
c=[9,17,25, 31,43]'

I wish to exclude all the elements that are c-0.5 to c+0.5

qw = 1:0.4:50;
c  = [9;17;25;1;43];
tol = .5;

(a) Bsxfun solution

Out = qw(~any(bsxfun(@ge, qw, c-tol) & bsxfun(@le, qw, c+tol)));

(B) Arrayfun solution

Out = qw(~arrayfun(@(x) any(x >= c-tol & x <= c+tol),qw))

c must be an integer. Then, a solution:

depth = [0.01 1.5:1.5:30]';
w = 10 - 0.5 .* depth;
w(w<0) = 0;
a=829862;
b=21
c=round(a/b)
W = repmat(w,c,1);

Before the loop:

iter = 0;

Then change the while to

while iter <= 5 && tol > 0
    iter = iter + 1;
