How do I get only the HR out of this .csv

Hi

I am trying read this file into Matlab and plot the Heartrate.

I am pretty confused what type of command I should use

Thanks for your Help!

If you post the file, or at least the first 20 lines or so, it would be easier to say which command is best to use. Generally, the command I would use is readtable, but I might edit the first lines to get a good header line before reading it. This is a good way to get an indication about how well readtable can pars your data:

opts = detectImportOptions('myCsvfile1.csv');
disp(opts)

For a csv with a single header line:

% read everything into a table
t1 = readtable('myCsvfile1.csv');
% select the data you want
t1 = t1.Var3;

For a csv file with an extra header line before the variable name header:

t2 = readtable('myCsvfile2.csv', 'HeaderLines',1);
t2 = t2.Var3;
