I need help doing this short program

user is to input T1 in the formate hh:mm:ss

user is to input T2 in the formate hh:mm:ss

TM= 12:00:00

Tz= TM+T1-T2 (output in hh:mm:ss form)

Ty=(Tz/2)+T2 (output in hh:mm:ss form)

Tx=(Tz/3)*2 (output in hh:mm:ss form)

Tn=(Tx+T2) (output in hh:mm:ss form)

Use duration function

% String
T1str = "02:30:31";
T2str = "08:06:45";
TMstr = "12:00:00";
% Convert to duration
T1 = duration(T1str)

T1 = duration
   02:30:31

T2 = duration(T2str)

T2 = duration
   08:06:45

TM = duration(TMstr)

TM = duration
   12:00:00

% Duration calculation
Tz= TM + T1 - T2 

Tz = duration
   06:23:46

% Do the rest yourself

Thanks, solution is OK, but I need program to prompt for the time of T1 & T2

[Chunru]

You can use "input" function which is not possible in on-line platform here. doc "input" in matlab.

I try to use input fuction

but what is the correct way to input time in the formate: hh:mm:ss?

[Chunru]

% T1str = "02:30:31";

% Change above into  the following
T1str = input("Enter T1 in format hh:mm:ss", "s");

% Do the same for T2str

[Moe Joe]

Perfect, thanks a lot dear Chunru...
