Though it seems weird to me, that this should be the reason - what can I change, that both files look 100% identical? The problem I'm having is that the white spaces have different lengths. How to skip them By the way, the number list is extra, not included in my file. The output file is lacking of the white spaces at the begin of every line, that seems to be the only difference of input and output file.

Param = textscan(fid,'%s','delimiter','\n') I'm loading it to Matlab and directly save it again without changes: % read original file I want to read the file and store 3 5 7 11 15 20 30 50 in one array and the float values in another. Except some white spaces, and the other software seems to react very sensitive on that. As it was not working I reduced my manipulation script to a minimum, so actually nothing is changed. read empty line by textscan Follow 22 views (last 30 days) Show older comments zhiwen wan on Vote 0 Link Edited: Rik on Accepted Answer: Rik Hi Everyone, I am trying to organize a txt file with 12000 lines, which is too large to use readtable. I know how to do it, and I didn't expected problems. txt-input files which I need to manipulate with Matlab. I am trying to organize a txt file with 12000 lines, which is too large to use readtable. The default is whitespace.To run a certain software I'm using. For backwards compatibility,īyte strings will be decoded as ‘latin1’. The character used to separate the values. The characters or list of characters used to indicate the start of aĬomment. comments str or sequence of str or None, optional Read Floating-Point Numbers Read Different Types of Data Remove Literal Text Skip the Remainder of a Line Specify Delimiter and Empty Value Conversion Specify Text to be Treated as Empty or Comments Treat Repeated Delimiters as One Specify Repeated Conversion. In thisĬase, the number of columns used must match the number of fields in Let's say MathWorks decides to create a MATLAB X release, which takes a big one-time breaking change that abandons back-compatibility and creates a more modern MATLAB language, ditching the unfortunate stuff that's around for historical reasons. MATLAB Functions textscan On this page Syntax Description Examples. Use fopen to open the file and obtain the fileID value. The text file is indicated by the file identifier, fileID. Structured data-type, the resulting array will be 1-dimensional, andĮach row will be interpreted as an element of the array. Description example C textscan (fileID,formatSpec) reads data from an open text file into a cell array, C. dtype data-type, optionalĭata-type of the resulting array default: float. 1 Try this - C textscan (fid, d,HeaderLines,Row-1) Row will specify the row of data that you want to extract from the text file. In a list or produced by a generator are treated as lines. That generators must return bytes or strings. Parameters : fname file, str, pathlib.Path, list of str, generatorįile, filename, list, or generator to read. loadtxt ( fname, dtype=, comments='#', delimiter=None, converters=None, skiprows=0, usecols=None, unpack=False, ndmin=0, encoding='bytes', max_rows=None, *, quotechar=None, like=None ) #
