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));

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
