How to convert time to a number?

I want to use a prompted input in the format HH:SS and convert it to a number. For example, 17:15 (17 mins, 15 secs) would be 17.25. Is there a function in MATLAB that does this?

prompt =('Please enter your time in the format MM:SS:  \n\n');

time = input(prompt);

reward = round(929187*time^(-3.235));

Answer 1

[prasanth s]

use following code to get values as string array.

time=input(prompt,'s');

split the output 'time' using split function with delimiter ':'

S=split(time,':');

then use following codes to convert the time

Easy way is: divide the seconds by 60 and add to minutes.

MATLAB way is:

D=minutes(17)+seconds(15);
M=minutes(D);

>> d = duration('17:15','Format','mm:ss')
d = 
  duration
   17:15
>> d.Format = 'm'
d = 
  duration
   17.25 min
