tse2001to2020.csv

I'm trying to read this CSV file, attached below. I tried:

x = dlmread('tse2001to2020.csv',',',2,1)

Because I'm trying to skip the header, but it gives me this error message:

Error using dlmread (line 147)
Mismatch between file and format character vector.
Trouble reading 'Numeric' field from file (row number
1, field number 3) ==>
/4/2002,12,4,2002,07:32:16,142,Total,1.024,2:04:00 AM\n
Error in HW7Prob3 (line 1)
x = dlmread('tse2001to2020.csv',',',

What am I missing here?

It won't work because you have strings in the lines. You can use readtable() though:

filename = 'tse2001to2020.csv';
t = readtable(filename)

I think you can but you're have to call it at least twice - basically send in row and column inputs but avoid the string column, where the string it 'Total'.

By the way, you're supposed to tag homework as homework so no one gives you the solution directly, which could get you in trouble if you turned in that solution as your own work. I've added the tag for you to help you avoid that problem.

Oh, sorry! Wasn't aware of that. I'll do that next time. Thanks for all the help!
