If a have a vector [93.60 119.15 136.19 191.55 238.39 268.20 302.27 340.60 383.18 425.77] and a number that every time is different.For example numb=410 i want to find the number 383.18 from the vector.

Use the find function:
vector = [93.60 119.15 136.19 191.55 238.39 268.20 302.27 340.60 383.18 425.77];
numb=410;
idx = find(vector <= numb, 1, 'last');
Result = vector(idx)
Result =
383.18

Star's answer works in the values in the vector are sorted. If not, min might be a better choice:
vector = [93.60 119.15 136.19 191.55 238.39 268.20 302.27 340.60 383.18 425.77];
numb=410;
[~, imin] = min(abs(vector - num));
vector(imin)
