# MATLAB: Separate empty cells (NaN) from others

empty valuesnan cellsseperate specific rows

I have a table of cells ( ex: 100*75 cell)
and i want to focus on column 12 , if any cell in it is NaN (empty) , i want to separate its row from the table.
i use this code:
 [ndata text alldata] = xlsread('mdr1.xls','sheet1');[R1,C1]=size(alldata);j=1;K=1;for i=1:size(alldata,1)    if isnan(alldata{i,12})        Ndate(j)=i;        j=j+1;    else        Ydate(K)=i;        K=K+1;    endendNAdate=alldata(Ndate,:);DDate=alldata(Ydate,:);xlswrite('separate.xls',DDate,1);xlswrite('separate.xls',NADate,2);
it works…
but
I wonder if anyone has an idea to modify this code.

c12=A(:,12)id12=~cellfun(@isnan,c12)out=A(id12,:)
out1=A(~id12,:)
