Hi all,

How can I write to file a cell of struct? For instance if I have

    a=struct('first',1,'second',2);
    b=struct('third',3,'fourth',4); myCell={a,b}.
  end
I cannot use something like this since that it requires the redefinition of the function fprintf:
  if true
    fileID=fopen(fileName, 'w');
    for l=1:size(myCell,1)
       fprintf(fileID,'%s,%s',myCell{l});
    end
    fclose(fileID);
  end

Thank you

Why not save to a .mat file?

For writing structs, strings, cells to file I once made the following programm: if you want to read the data back out of the file use the command fopen('exp','r')

%Madup input value's
clear
%string
DataStruct.NUL = 'Header';
%long number with dots
DataStruct.FILEID = '2.0.0.0.0.0.1';
%array in struct one 
DataStruct.EEN = [1 : 10];
%array in struct two   
DataStruct.TWEE = [2 : 11];
%array in struct three
DataStruct.DRIE = [3 : 12];
%array in struct four
DataStruct.VIER = [4 : 13];
%array in struct five
DataStruct.VIJF = [5 : 14];
%Cell in struct 
DataStruct.ZES = {5 : 14};
%string
DataStruct.CLOSE = 'Close';
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Write DataStruct to file
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%open a file to write your data to I named this exp
fid =  fopen('exp','w');
NUL = DataStruct.NUL;
fprintf(fid, '%s\n', NUL);
FILEID = DataStruct.FILEID;
fprintf(fid, '%s\n', FILEID);
str = [];
for ii = 1:length(DataStruct.EEN)
  str = [str, ' ', num2str(DataStruct.EEN(ii))];
end
EEN = num2str(str);
fprintf(fid, '%s\n', str);
str = [];
for ii = 1:length(DataStruct.TWEE)
  str = [str, ' ', num2str(DataStruct.TWEE(ii))];
end
TWEE = num2str(str);
fprintf(fid, '%s\n', str);
str = [];
for ii = 1:length(DataStruct.DRIE)
  str = [str, ' ', num2str(DataStruct.DRIE(ii))];
end
DRIE = num2str(str);
fprintf(fid, '%s\n', str);
str = [];
for ii = 1:length(DataStruct.VIER)
  str = [str, ' ', num2str(DataStruct.VIER(ii))];
end
VIER = num2str(str);
fprintf(fid, '%s\n', str);
str = [];
for ii = 1:length(DataStruct.VIJF)
  str = [str, ' ', num2str(DataStruct.VIJF(ii))];
end
VIJF = num2str(str);
fprintf(fid, '%s\n', str);
str = [];
for ii = 1:length(DataStruct.ZES)
  str = [str, ' ', num2str(cell2mat(DataStruct.ZES(ii)))];
end
ZES = num2str(str);
fprintf(fid, '%s\n', str);
str = [];
CLOSE = DataStruct.CLOSE;
fprintf(fid, '%s\n', CLOSE);
