Hi,
I'm trying to read the attached csv file, but both csvread is having trouble to parse through line 8010 of the second column (Input) of the file, where the values have a $ concatenated. This is the error message I get:
>> a = csvread('test.csv',2,0)
Error using dlmread (line 147)
Mismatch between file and format character vector.
Trouble reading 'Numeric' field from file (row number 8011, field number 1) ==> $\n
Error in csvread (line 48)
m=dlmread(filename, ',', r, c);
I tried using readtable as well, but the Input column characters would be stored as cells, and converting that column to a matrix didn't work.
My end goal here would be loading the file to a table, while replacing the invalid characters with either NaN or zero. What's the best way to achieve it? Thanks!

datacell = textscan( regexprep( fileread('test.csv'), '\$', '0' ), '%f%f', 'delimiter', ',', 'HeaderLines', 1);
Duration = datacell{1};
Input = datacell{1};
YourTable = table(Duration, Input);
