I have a vector of time in format HH:SS in a table and I want to convert it to a decimal number.
For example:
03:30 = 3.5
04:45 = 4.75
How can I do that?
Thanks.

Ran in:
If you have them stored as a duration array just use the hours function.
du = duration({'03:30', '04:45'}, 'InputFormat', 'hh:mm')
du = 1×2 duration array
03:30:00 04:45:00
hours(du)
ans = 1×2
3.5000 4.7500

Ran in:
v = datetime({'03:30', '04:45'}, 'InputFormat', 'HH:mm')
v = 1×2 datetime array
30-Aug-2021 03:30:00 30-Aug-2021 04:45:00
hour(v) + minute(v) / 60
ans = 1×2
3.5000 4.7500
