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

4 次查看(过去 30 天)
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

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

function m = May2015
for i = 1:31
[DateNumber, DateName] = weekday(datenum([2015 5 i]));
m(i) = struct('month','May','date',i,'day', DateName);
end

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

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
