Reading first column of a .csv file
Ältere Kommentare anzeigen
Hi everyone, I'm having some difficulty getting the information I'm looking for extracted. I would like to pull everything from the first column from rows 2 to the end. When I use txtread I extract the entire document, I've tried a few other read functions however they produced errors. Any help would be greatly appreciated, I've attached the .csv file and the script producing the .csv file. Thanks in advanced and hope you all have a great weekend. Zack
fu=['https://raw.githubusercontent.com/datasets/s-and-p-500-companies/master/data/constituents-financials.csv'];
urlwrite(fu,'Symbols.csv')
symbols=textread('symbols.csv','%s');

fid = fopen('symbols.csv', 'rt');
datacell = textscan(fid, '%[^,]%*[^\n]', 'HeaderLines', 1);
fclose(fid);
symbols = datacell{1};

You can use importdata as shown below:
symbols = importdata('Symbols.csv');
column_1 = symbols.data(:, 1);
This should get your first column without the header.
