I currently have a cell array filled with times like the below. I am trying to convert this into a usable format so that I can use the times in a plot. Does anyone know how I would do this? I have tried using str2double but this returns the values as NaNs. Someone also suggested that I used regexp but this resulted in the same outcome.

'000:00h:00min:23:743:990µs'

I don't understand the format. What's 23:743:990?

000days:00hours:00min:23sec:743ms:990µs.

Does this make more sense?

在 MATLAB Online 中打开

Join the cell string to a string at first, then parse it by sscanf:

C = {'000:00h:00min:23:743:990µs', '000:00h:00min:23:743:990µs'};
S = sprintf('%s*', C{:});
V = sscanf(S, '%d:%dh:%dmin:%d:%d:%dµs*', [6, inf]);

Hi Jan, this is very close to what I would like to achieve, thanks. This currently lists each time as a column. My preferred output would be a single double for each time so as I can use it for the x axis on a plot. Is this possible?
