MATLAB: How to read a .txt file into Matlab

readfile

I'm trying to get Matlab to read a .txt file into a string. I'm using the function readfile and can't get it to work. I have a .txt file saved in the correct directory called "April.txt" and I'm trying to say readfile(April.txt) or readfile('April.txt') and neither works. The error messages are Undefined variable "April" or class "April.txt". and Undefined function 'readfile' for input arguments of type 'char'. respectively.

Not "readfile" but "fileread":

fileread('April.txt')

Or even better with an absolute path

fileread(fullfile(Folder, 'April.txt'))

Read it using these lines

filetxt = fileread('m1.txt');
filetxt = strrep(filetxt, ',', '.');
data = cell2mat(textscan(filetxt, '%f%f%f%f'))

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);
