Question

use matlab to solve it

1. Write a function called MyTimeConversion with the following function declaration line. begin code function [Hours, Minutes, Message] = MyTimeConversion (TotalMinutes) end code The input argument TotalMinutes should be a nonnegative scalar integer representing the total number of minutes in a specified time interval. The output arguments Hours and Minutes should be nonnegative scalars such that Hours*60 + Minutes = TotalMinutes and the value of Minutes must be less than 60. The output argument Message must be a char array. A few examples below illustrate what it's properties should be. Notice that time units should be singular (i.e. minute, hour) if the value is 1, and plural (i.e. minutes, hours) if the value is not equal to 1 (including 0). Also, if TotalMinutes equals 1, the verb should be is instead of are. • For TotalMinutes = 151, Message should equal the char array 151 minutes are equal to 2 hours and 31 minutes.' 1 of 7 E7 - Prof. Alam Fall 2019, UC Berkeley • For TotalMinutes = 84, Message should equal the char array '84 minutes are equal to 1 hour and 24 minutes.' • For TotalMinutes = 60, Message should equal the char array 60 minutes are equal to 1 hour and 0 minutes.' • For TotalMinutes = 181, Message should equal the char array 181 minutes are equal to 3 hours and 1 minute.' • For TotalMinutes = 1, Message should equal the char array *1 minute is 0 hours and 1 minute.'

Answer 1

%The function MyTimeConversion that takes total minutes as input to the function
%Then find the total number of hours and total number of minutes for given total minutes
%The result of the function is stored in the Hours, Minutes and Message values

%Save this below code file as MyTimeConversion.m and run the file with the function name from Matlab as shown in %sample %output

-----------------------------------------------------------------------------------------------------------------

%MyTimeConversion.m
function[Hours, Minutes, Message] =MyTimeConversion(TotalMinutes)

%Divide TotalMinutes by 60 and get its floor value
%call floor method to get Hours
Hours=floor(TotalMinutes/60);
%call mod method to get Minutes as remainder value
%by dividing the TotalMinutes by 60
Minutes=mod(TotalMinutes,60);
  
%Concatenate the strings using strcat function
%num2str converts the number to string type
Message=strcat(num2str(TotalMinutes)," minutes are equal to ",num2str(Hours)," hours and ",
num2str(Minutes)," minutes");

end

Sample Output:

>> [Hours, Minutes, Message] =MyTimeConversion(151)
Hours = 2
Minutes = 31
Message = 151 minutes are equal to 2 hours and 31 minutes

>> [Hours, Minutes, Message] =MyTimeConversion(120)
Hours = 2
Minutes = 0
Message = 120 minutes are equal to 2 hours and 0 minutes

>> [Hours, Minutes, Message] =MyTimeConversion(600)
Hours = 10
Minutes = 0
Message = 600 minutes are equal to 10 hours and 0 minutes
