You can use ismember() with its second output argument:

% Machine Times
% Work    times
lookup = [ ...
1             3
2             5
3             12
4              8                    
5              9
6              7
7              10
9              5
10            2];

M = [ ...
10
5
9
1];

[~,idx] = ismember(M,lookup(:,1)); % idx: row in the first column of lookup where each element of M occurs

result = [M lookup(idx,2)] % result is M followed by corresponding elements from column 2 of lookup

result = 4×2
