Hi all,
I want to read the vectors which are hh:mm:ss (14:35:59.812) format and convert it to seconds. How can I do this in matlab?

Is this what you are looking for?
t='14:35:59.812';
[Y, M, D, H, MN, S] = datevec(t);
H*3600+MN*60+S

On R2016a I get the expected result
>> dt = datestr( now,'HH:MM:SS,FFF')
dt =
12:58:26,797

I want to convert Time column ( HH:MM:SS) to min, there is a direct command time2num but it requires toolbox and it's paid.So without using time2num how can I convert into minutes. I tried with datetime also but I got error.
table=readtable('sample.csv'):
times = datetime(table.Time,'InputFormat','HH:mm:ss:SSS');
times = hour(times).*60 + minute(times) + second(times)./60;

The first and the last cell returns the result I think you are looking for. See help on DATENUM
datenum( '14:35:59.812', 'HH:MM:SS.FFF' ) .* (24*60*60) - ...
datenum( '00:00:00.000', 'HH:MM:SS.FFF' ) .* (24*60*60)
datestr( datenum( '00:00:00.000', 'HH:MM:SS.FFF' ), 'yyyy-mm-dd' )
datenum( '14:35:59.812', 'HH:MM:SS.FFF', 0 ) .* (24*60*60)

About 100 times faster is:
t='14:35:59.812';
seconds=sum(sscanf(t,'%f:%f:%f').*[3600;60;1]);

t='14:35:59.812';
F = 'hh:mm:ss.SSS';
du = duration(t, 'InputFormat', F, 'Format', F)
format longg % To make s look nicer
s = seconds(du)
