Note that the empty fields results in NaN values. While ~isequal(nextLine, -1) % Loop while not at the end of the file For example, I create some csv file like your: q 1 2 3 4 5 6 7 csvwrite('csvlist4.csv',q,2,0) All troubles is to add some string to csv - it's because we need to combine numeric and text data. NextLine = fgetl(fid) % Read the first line from the file If you need to add string to your csv file. LineIndex = 1 % Index of cell to place the next line in M csvread (filename,R1,C1) reads data from the file starting at row offset R1 and column offset C1. The file must contain only numeric values. LineArray = cell(100, 1) % Preallocate a cell array (ideally slightly M csvread (filename) reads a comma-separated value (CSV) formatted file into array M. Here is the resulting code, placed in a function read_mixed_csv: function lineArray = read_mixed_csv(fileName, delimiter)įid = fopen(fileName, 'r') % Open the file For example, I create some csv file like your: q 1 2 3 4 5 6 7 csvwrite ('csvlist4.csv',q,2,0) All troubles is to add some string to csv - it's because we need to combine numeric and text data. Let's take a look at some of them: If you need to add string to your csv file. I am thinking the problem is because the list has '', but I do not know how to fix it. But Matlab does not recognize the comma as a delimiter. Then I used the function textscan to parse each line into separate strings using a predefined field delimiter and treating the integer fields as strings for now (they can be converted to numeric values later). 1 Answer Sorted by: 1 There are several approaches are possible here. Link Commented: Stephen23 on Accepted Answer: Star Strider ShipData.csv I need to import. I first used the function fgetl to read each line of the file into a cell array. Please someone tell me the procedure of importing such data. Using 'csvimport' I'm able to capture only the numeric values not the strings in the data. The readtable function automatically detects the header and the number of lines to skip. If you click the Import button, you can also see the generated code or script. Accepted Answer 1 Use the xlsread function with at least two (and at best all three) outputs: Theme Copy totalData,str,raw xlsread ('FED-RXIUSNBUK.csv') The ‘str’ variable should have your dates as a cell array of strings that you can use as an argument to datenum to convert them to date numbers. you will be able to choose what data types are imported. However, if you don't know a priori how many columns are in your file, you can use a more general approach like I did in the following function. 1 Link Commented: ehsan ghane on I have data files (.csv of course) which contains several columns each with a column header. To import data from a CSV file into MATLAB use the readtable function. csv file you can use the Import Tool which will help you through the import process. For the case when you know how many columns of data there will be in your CSV file, one simple call to textscan like Amro suggests will be your best solution.
