Read in a file with no spaces and write one part of each line into a file

Hi,

I have a data file with around 180 lines, like the following:

Date Time ,Frequency:

2019-09-11T11:43:02.782Z,9.0694850E+4

2019-09-11T11:43:07.776Z,9.0693890E+4

2019-09-11T11:43:12.779Z,9.0694460E+4

2019-09-11T11:43:17.781Z,9.0693870E+4

2019-09-11T11:43:22.775Z,9.0693370E+4

As you can see there are no spaces between date, time, and frequency determined:

How can I write a matlab script that can take this in and only give me the frequencies: so something like this:

9.0694850E+4

9.0693890E+4

9.0694460E+4

9.0693870E+4

9.0693370E+4

Thank you for your help,

However if you only need the frequencies and nothing else, then a plain readtable() and then access the second variable. Or detectImportOptions and set the SelectedVariables of the options to only select the second column, and then readtable()

Hi,

You can use importdata and access the frequencies by:

c = importdata('filename',',',1);
c.data
