csvread: Trouble reading 'Numeric' field from file
显示 更早的评论
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);
