MATLAB: Write data to header file

i have 1×800 double and i need to outpu in header file all this values like this; float sineTable[800] = { /* values go here */ };

How abou the following?

% Sample data
data = rand(1,800);
% Arrange it to comma-separated string
str = num2str(data);
str = regexprep(str,'\s+',',');
% Save as 'sample.h' file
fid = fopen('sample.h','w');
fprintf(fid,'sineTable[800] = {%s};\n',str);
fclose(fid);

You are closing the file in the loop. close the file after the loop. I assume the below should work.

function read_datapattern(filename)
fid = fopen(filename,'rt');
if fid < 0
  error('error opening file %s\n\n',filename);
end
pattern = fgets(fid);
for n = 1:32767
  nextline = fgets(fid);
  pattern = strcat(pattern, nextline);
fprintf(pattern);
fprintf('\n');
end
fclose(fid);

How about the following?

% Read txt file
fid = fopen('data1.txt','r');
strData = textscan(fid,'%s','Delimiter','\r\n');
strData = strData{1};
fclose(fid);
% Eliminate empty line(s) and the line(s) which contains '--'
idx1 = cellfun(@isempty,strData);
idx2 = contains(strData,'--');
strData = strData(~idx1 & ~idx2);
% Insert space before '#'
strData = replace(strData,'#',' #');
% Replace 3 or more consecutive spaces to 2 consecutive spaces
strData = regexprep(strData,'\s{3,}','  ');
% Prepare the output cell array
outData = cell(size(strData,1),6);
% Split each line with 2 consecutive spaces
for kk = 1:size(strData,1)
  c = strsplit(strData{kk},'  ');
  outData(kk,[1:numel(c)-1, end]) = c;
end
% Save as Excel file
writecell(outData,'result.xlsx');
