![]() ![]() The readtable function automatically detects the header and the number of lines to skip. If not, you'll simply get only the first row in your matrix. To import data from a CSV file into MATLAB use the readtable function. Note that this will only work if MATLAB indeed "sees" the 5th line like you described. You can make textread do that by using the 'headerlines' option: C = textread('file.txt', '%s', 1, 'headerlines', 4, 'delimiter', '\n')Īnd then use the code that employs regexp to split the string str. Ideally, I would like to tell Matlab to skip to Row-5, then start reading data. Regarding the second part of the question: Then turn the strings into numbers and convert everything into a matrix: C = C, 'Uniform', false) You can use the almighty regexp to for that: C = regexp(str, '\$,', 'split') If you click the Import button, you can also see the generated code or script. you will be able to choose what data types are imported. I don't know how you managed to read this data as one line, but suppose you did and you want to split it. csv file you can use the Import Tool which will help you through the import process. Is there a way to detect the "$" and reformat the data into a usable matrix form? Ideally, I would like to tell Matlab to skip to Row-5, then start reading data and creating a new line in the matrix every time it encounters a "$". ![]() First column is string type and others are numeric. Just like the picture below shows, I import all the variables into a matrix 'X', then I would like to import the header one by one to rename all the columns. MATLAB Answers - MATLAB Central How to read string data from a csv file Follow 424 views (last 30 days) Show older comments Kavita Navria on 0 Link Commented: Guodong Cui on Accepted Answer: KSSV Hello. txt file "Data Matlab sees", I cant find a way to tell Matlab how to read. 1 I want to import a row of headers form Excel into matlab then put each header into its according variable's name in MATLAB. I have no problem importing the format seen by "wordpad (re-saved with)" using "csvread" and skipping column 1, but for the raw. The file is in the format below, the problem is that matlab does not seem to recognize the "new line" character indicators following every "$", so matlab just sees the 5th line as a continuous stream of data The readmatrix function performs automatic detection of import parameters for your file. you should post a couple of rows from your CSV file so that we get an idea how the file is structured (are the strings quoted with ' or ', do they contain commas inside the quotations, are the integer values quoted as well, is there any escaped delimiters such as 'this is \'an example\'' etc. I have a question regarding the importing of. Syntax A readmatrix (filename) A readmatrix (filename,opts) A readmatrix ( ,Name,Value) Description example A readmatrix (filename) creates an array by reading column-oriented data from a file.
