I did this earlier but know it does not work. I'm trying to reformat a text file and print another one. When I run the code I turns back the following error:

Error using fprintf
Function is not defined for 'cell' inputs.
Error in P_format (line 36)
fprintf(fid, '%s %4s %4s %4s %4s %4s %4s\n', Pswmm{i,:});

Here is the code:

clear all
clc
%Format text data from NCDC website into SWMM5 compatible P .txt file
fid = fopen('C:\Users\sdehoyos\Desktop\Precip_448903Dulles_448906Reagan.txt');
A = textscan(fid, '%s %d %s %f', 'HeaderLines', '1'); 
fclose(fid);
COOPstationID=cellstr(cell2mat(A{1,1}));
Date=cellstr(num2str(A{1,2}));
Time=cellstr(cell2mat(A{1,3}));
Ptimes100=A{1,4};
for i=1:length(COOPstationID)
  stationID{i,:}=cellstr({COOPstationID{i}(6:end)});
end
for i=1:length(Date)
  Year{i,:}=cellstr({Date{i}(1:4)});
  Month{i,:}=cellstr({Date{i}(5:6)});
  Day{i,:}=cellstr({Date{i}(7:8)});
end
for i=1:length(Time)
  Hour{i,:}=cellstr({Time{i}(1:2)});
  Minute{i,:}={Time{i}(4:5)};
end
P=cellstr(num2str(Ptimes100/100));
Pswmm={stationID Year Month Day Hour Minute P};
fid = fopen('Pswmm.txt', 'w');
for i=1:length(Pswmm);
fprintf(fid, '%s %4s %4s %4s %4s %4s %4s\n', Pswmm{i,:});
end
fclose(fid);
