how to make function that return struct vector whose elements are days of month

Hi every one; I am going to attempt that query: a function called May2015 that returns a struct vector (row or column) whose elements correspond to the days of May, 2015. Each struct should contain three fields with these (exact) field names: “month”, “date”, and “day” (all lower case). • The month field must contain the string 'May' (uppercase ‘M’). • The date field must contain a scalar of type double that equals the date (1 through 31). • The day field must contain the three-letter abbreviation of the day chosen from this list: 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'. For example, here is a call of the function followed by a command that shows the eleventh element of the struct array that is returned by the function:

>> m = May2015;
>> m(11)
ans =
month: 'May'
date: 11
day: 'Mon'

I am using that code

function M=May2015(a)
M=strut('month','May','date',a)
end

I have no idea how i can set the day like mon,tues,wed,thus,fri sat,sun, corresponding date no. May month start from 1 to 30 and the day on 1 was mon and of 30 was tues. Kindly guide me how can i mange day (string) with date. I think i have to use for loop but not idea.. Thanks in advance

Is this homework? If so, can you add 'homework' as a tag?

how to write the name of month also(for example 2 as input will give an output of February)

Answer 1

[Augusto Oliveira]

It's m = May2015, not m = May2015(n)... i = 1:31

[Augusto Oliveira]

function m = May2015

for i = 1:31
    [DateNumber, DateName] = weekday(datenum([2015 5 i]));
    m(i) = struct('month','May','date',i,'day', DateName);
end

@Augusto thanks for contributions. Why we not set input argument n to May2015??

Answer 2

[Andrei Bobrov]

function out = May2015
[~,k] = weekday(datenum(2015, 5, (1:31)'));
out = struct('month','May','date',num2cell((1:31)'),'day',cellstr(k));

use:

>> m = May2015
m =

    31x1 struct array containing the fields:

      month
      date
      day

>> m(11)
ans =

    scalar structure containing the fields:

      month = May
      date =  11
      day = Mon

@Andrei thanks for contributions.. i use that code

function out = May2015(n)
[~,k] = weekday(datenum([2015 5 n]));
out = struct('month','May','date',n,'day',k);
end

and in testing getting that error

Your solution is _not_ correct.

[Titus Edelhofer]

Muhammad, the answer of Andrei is not missing a lot. If you want to have a struct array, you can either use looping on Andrei's solution, i.e.,

for i=1:length(n)
  out(i) = struct('month', 'May', 'date', n(i), 'day', k(i));
end

or use cell arrays for initialization

nc = num2cell(n);
out = struct( ...
  'month', 'May', ...
  'date',  nc, ...
  'day',   k);

@Titus i am revolving around the question.but not finding the solution??

[Ishaan Kaushal]

in 2nd line what is the purpose of (~) symbol.

See ignore function outputs.

@Titus thanks for contributions.. I very new to programming ... create more easily solution for me...

Answer 4

[charu sharma]

you need to mention the number of dates in MAY that is 1 to 31 and days Here is the more simple solution for you: http://farzicoders.blogspot.in/2015/08/write-function-called-may2015-that.html
