Gil - is each element of your cell array a numeric scalar or numeric array? See cell2mat which provides some examples on how you might do this conversion.

Try str2double:
cell2mat({'01'}) = '01' (double)
str2double({'01'}) = 1 (char)

The absolute easiest way I know is comma seperated list assignment, which looks like this;
a = [{25}; {31}; {24}; {5}; {23}; {64}; {12}; {53}; {22}];
b = [a{:}]'
b = 9×1
25 31 24 5 23 64 12 53 22
I don't know whrether it is any good, but it works if the values of all cells are of the same type. just keep in mind that it will transpose a columnvector to a rowvector.
