![]() ![]() You'd access the values in the other two variables using the normal indexing notation (i.e. When the field width operator is used with single characters ( c ), textscan also reads delimiter, white-space, and end-of-line characters. Now if you want to split up the columns into separate variables, just access the right cells: names = C where ii is the name you want to access. So in your example when processing 'a,b,' with q it first processes the a as part of the q format, and then eats the delimiter that is there, leaving 'b,' in the. Take note that the formatting string has no spaces because the delimiter flag will take care of that work. Well, it tells us that after textscan finishes processing the format, it examines the input stream, consuming Whitespace and up to the first copy of the Delimiter, and then stops. I can use h as a delimiter, but I cannot use. 1 Using textscan I'm trying to read a file that has comma separated data in the following format: '1234','24.0','Hello, my name is Joe' '4567','25,0','Hi, I'm Jane' The non-delimiter comma in the third field are problematic and I ultimately don't want the '' around the pieces of data. You'd then close the file after you're done using fclose.Īs such, you just do this: File = Ĭ = textscan(f, '%s%f%f', 'Delimiter', ',') I want to use h as a single delimiter to extract the letters after h with textscan function. This is done by using the Delimiter option in textscan and you specify the, character as the delimiter character. ![]() You also need to specify the delimiter to be the, character because that's what is being used to separate between columns. Also, you really only need one output variable because each "column" will be placed as a separate column in a cell array once you use textscan. You first need to open up the file with fopen which provides a file ID / pointer to the actual file. The file comes out of a relational database (Antelope) and consists of earthquake location, dates, times, phase information, etc. I've tried the following: file = '0.Horchler is indeed correct. Learn more about text file, block, textscan, text, read, parse, debug, debugging session, regexp, blocks MATLAB I have a text file that is in a rather funky format. What formatSpec should I use so that I get the coordinates of each region outputed in a cell? I know I have to use textscan to accomplish this but I am unsure of the formatspec options needed to achieve this, since whichever setting I use seem to give me some jumbled form of cell output. These are coordinates to regions of interest for each category in an image. in 1,1 there is only 'C', despite being a 2x1 Cell. file fopen ('file.txt') d textscan (file,'s d d d ,'delimiter',',') If i run the code above it gives me a 1 x n array. Theme Copy textscan (a,'sfffffs','Delimiter',' ') that is how i tried it. I want to read a text file into a cell array so that i have each line of my file as a new row and each attribute in my file as a column on that row.
