If importdata recognizes the file extension, it calls the MATLAB helper function designed to import the associated file format (such as load for MAT-files or xlsread for spreadsheets). Otherwise, importdata interprets the file as a delimited ASCII file.

MATLAB is commonly used for analysis of large data sets, which are typically read from a file. The file may have been generated by a data acquisition system or downloaded from a web page. Most often it is in ASCII (plain text) or spreadsheet (e.g. Excel) format.

I have a .ascii file as below for 1980-2010: How can I choose the data from ANOM4 column and corresponding month(MON), without the header, using matlab?

Jun 3, 2011 · Since ASCII characters are encoded as unsigned 8-bit integers, you can store them as a UINT8 data type in MATLAB. You can use the UINT8 function to get the ASCII values of a character string.

This section describes how to use MATLAB functions to export data in several common ASCII formats. For example, you can use these functions to export a MATLAB matrix as a text file where the rows and columns are represented as space-separated, numeric values.

Mar 12, 2013 · I have to import ASCII files in MATLAB and then have them read. These are the functions I tried out with: 1) load(filename) does not work: it says "number of columns on line 2 of ASCII file must be the same as previous lines" 2) textscan(file, '-ascii') returns something like "Empty cell array: 1-by-0

MATLAB® stores all characters as Unicode® characters using the UTF-16 encoding, where every character is represented by a numeric code value. (Unicode incorporates the ASCII character set as the first 128 symbols, so ASCII characters have …

Feb 3, 2011 · If you don't know the number of columns in advance then you will have to read the file one line at a time. If you call textscan with a single %s and no limiting number, it will read N number of strings from the line.

Oct 15, 2012 · I need help on how to load/read the ASCII files. I have files that are in a .A01 format but I dont know if I am supposed to changed it to .txt in order for MATLAB to run it? Thanks!
