![]() 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. ![]() ![]() I can use h as a delimiter, but I cannot use. For example, I would like to read the following data using. 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 want to use h as a single delimiter to extract the letters after h with textscan function. 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. Lets say some numeric data is not delimited, buth we can delimit it based on their location. 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. Theme Copy textscan (a,'sfffffs','Delimiter',' ') that is how i tried it. You'd access the values in the other two variables using the normal indexing notation (i.e. So what I wanted the textscan to output was a 4 row cell array, the first row would have 6 cells representing the coordinates of the 6 regions for that specific row(in this case leaf tips). The string is: a 'C +01.314 +027.11 +01.225 +01.578 +01.579 Air' directly visible is that 'Air' has 4 spaces, every other value just one and a sign. ![]() 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. Take note that the formatting string has no spaces because the delimiter flag will take care of that work. For example: a,142,5 aa,3,0 abb,5,0 ability,3,0 about,2,0 I want to read the file and put the words in one variable, the first numbers in another, and the second numbers in another but I am having trouble with textscan. 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', ',') txt file with rows consisting of three elements, a word and two numbers, separated by commas. This is done by using the Delimiter option in textscan and you specify the, character as the delimiter character. Each row is delimited by an end-of-line ( EOL) character sequence. Each field consists of a group of characters delimited by a field delimiter character. Each block consists of a number of internally consistent fields. ![]() You also need to specify the delimiter to be the, character because that's what is being used to separate between columns. The textscan function regards a text file as consisting of blocks. 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. ![]()
