Convert cell array of latitudes to array

I have a array of cells containing latitudes in the format {'50.01.234';'etc} how can i convert this into something meaningfull in which i will be able to produce a grid from later?

Is 50.01.234 to be a single specification? For example does it mean 50 degrees, 01 minutes, and 234 seconds, which would be the same thing as 50 degrees, 4 minutes and 54 seconds?
sorry i should have specified this. Its actually deg and decimal , so 50.01.234 would be 50degrees and 01.234 minutes. i would like to be able to take them from the array of cells eventually to be able to plot the points on a grid map

k = {'1' ; '3' ; '4' ; '7' ; '10'} ; % be your cell array
N = length(k) ; % gives number of elements in cell array
lon = zeros(N,1) ; % Initialize the lon array
for i = 1:length(k) % Loop for every element
lon(i) = str2num(k{i}) ; % combert sring/ char to number
end

I'm affraid this hasn't worked, it handles numbers such as your example fine but it does not handle the second decimal point well such as 50.01.234

Are you sure that you get 50 deg, 1.234 min and not 50 deg 1 min 234 sec (while the last value is a typo only)?
Data = {'50.01.234'; '60.06.345'};
Str = sprintf('%s#'m Data{:});
Value = sscanf(Str, '%i.%f#', [2, numel(Data)]);
Deg = Value(1, :) + Value(2, :) / 60;
paired_numeric = str2double( regexp(TheCellArray(:), '\.', 'split', 'once') );
degrees = paired_numeric(:,1) + paired_numeric(:,2) / 60;
