![]() PS I'm using octave and textscan is not compatible with it. How can I get it so when I type m_s(1,2) I get back the whole field example I would like to read in the file as a string array of seperated strings so I can index the elements in the array. If str is a character array with more than one row, sscanf reads the characters in column order. I want to skip the first two lines with text and blank, and read the rest into a matrix A. The sscanf function repeatedly applies formatSpec to sequences of characters in str until it either reaches the end of str or fails to match formatSpec to a sequence of characters. I also have another file, which has six columns instead of two. When I access a cell like m_s(1,2) I get back a single letter instead of a field. Hello, I have a text file that contains one column of words. Hi, I have attached a txt file which I want to read onto a matrix. Create a sample file, read all the data in the file, and then read only a. M_s = fscanf(fid,'%f %f %s %s %f %f %f') This example shows how to import comma-separated numeric data from a text file. I'm having a problem with fscanf and using comma delimited data fid = fopen('/tmp/freq_range_color_coded.txt') I then want to export it to several files based on the same Resonance Freq. ![]() Note however, that textscan allocates memory for the number of lines you provide (1000 here), so you want to. A value of 1 or true instructs textscan to concatenate consecutive columns of the same class in the output cell array. Which command should I use if I'm importing data. The command seems to work fine if I only have a vector in the text file, but if I have a matrix, matlab will change the structure of the data and store the matrix as a vector. Here's the entire file (not sure pasting here is the right way to do this - i'm new to both matlab and stackoverflow.I have a comma delimited single text file with strings and integers that I'm trying to import into a cell array. Use the following: fh fopen ('indices.txt') resC textscan (fh, 'd d d d d d d s', 1000) res cell2mat (resC (1:7)) fclose (fh) textscan will only read (and return) up to the available number of lines. Is textscan the correct command to use when importing data from text files into matlab. (I've also tried a number of variations, such as defining the delimiter as ' ', with the same result) Matlab's textscan() function deals with this very neatly, as you can do this: array textscan(fid, 'field1d field2d field3d ' and you will get back a cell-array where each column contains the respective field, and the text is simply ignored. I also tried to specify the date and time using datetime format: time = textscan(fid,'%s %D')īoth of these just produce a blank cell. I first tried to specify these as strings ( %s): fid = fopen(fname) I figured there are 3 columns of this row, with single white space as delimiter. Learn more about matrix, matrix array, data, for loop, image, matlab MATLAB I am writing a function which reads a text file with some header information in the first 10 lines and then the actual data starts. I've tried using textscan, which I have used before for similar problems. I have a number of text files with data, and want to read a specific part of each file (time information), which is always located at the end of the first row of each file.
