MATLAB: Missing data values with interpolation

interpolationnan

Hello everybody,
I have a cell array each containing a sequence of diferent values. The sequences contains some missing values (I've represented with NaN). I would like to replace all this NaN places with numbers. I think the better way is do an interpolation but I don't know how to code this Nan and how to save it on a table in Matlab.
I1= interp1(x,y,'linear');
Greetings,
Pd) I've tried this but it doesn't work
nanData = isnan(y);
index   = 1:numel(y);
data2   = y;
data2(nanData) = interp1(index(~nanData), y(~nanData), index(nanData));

x={ 1  2  3  4  5  6  7  8 9 10}
y={ 0.3850 NaN  3.0394 NaN  0.6475  1.0000  1.5000  NaN  1.1506  0.58}
x=cell2mat(x);y=cell2mat(y);
xi=x(find(~isnan(y)));yi=y(find(~isnan(y)))
result=interp1(xi,yi,x,'linear')
