Reading a table of strings is more complex, since the strings have to be the same length. Read a text file into a matrix with one row per input line. I want to read a regular text file into cell array at the matlab. How can i do that? I don't want any formatting. Reading as literals. How to read lines into cell array at the matlab. In your question and question title does not help people to find your question. Tags stand alone, meaning tagging with.
Just use textscan with different format specifiers. Fid = fopen(filename,'r'); heading = textscan(fid,'%s%s%s',1); fgetl(fid);%advance the file pointer one line data = textscan(fid,'%n%n%n');%read the rest of the data fclose(fid); In this case 'heading' will be a cell array containing cells with each column heading inside, so you will have to change them into cell array of strings or whatever it is that you want. 'data' will be a cell array containing a numeric array for each column that you read, so you will have to cat them together to make one matrix.
Reading Strings Line by Line from Text Files:: Data Import and Export (Programming) Programming Reading Strings Line by Line from Text Files MATLAB provides two functions, fgetl and fgets, that read lines from formatted text files and store them in string vectors. The two functions are almost identical; the only difference is that fgets copies the newline character to the string vector but fgetl does not. The following M-file function demonstrates a possible use of fgetl. This function uses fgetl to read an entire file one line at a time.
For each line, the function determines whether an input literal string ( literal) appears in the line. If it does, the function prints the entire line preceded by the number of times the literal string appears on the line. function y = litcount(filename, literal)% Search for number of string matches per line. Fid = fopen(filename, 'rt'); y = 0; while feof(fid) 0 tline = fgetl(fid); matches = findstr(tline, literal); num = length(matches); if num 0 y = y + num; fprintf(1,'%d:%s n',num,tline); end end fclose(fid); For example, consider the following input data file called badpoem:.

Oranges and lemons, Pineapples and tea. Orangutans and monkeys, Dragonflys or fleas. To find out how many times the string 'an' appears in this file, use litcount:. litcount('badpoem','an') 2: Oranges and lemons, 1: Pineapples and tea. 3: Orangutans and monkeys, Controlling Position in a File Reading Formatted ASCII Data © 1994-2005 The MathWorks, Inc.
