Question

MATLAB ONLY:

Find oldest house on the market?

can't not use any built in function except length and isnan to write this function if necessary .

Inputs:

dateConstruct - an array that will be linked to when each house was build

dateRebuild - an array that will be linked to when eeach house was rebuild. However if an house has never been rebuild, the year will be Nan.

Outputs:

Numb - will serve as the index location for the oldest standing house in the neighborhood.

Example: DateConstruct= [ 2025 2030 2015]; dateRebuild = [ 2030 Nan 2056]

then ind = [1, 2] because their is a tie for the oldest house standing. should also be able to display if its just 1 house or two without an issue.

function [Numb] = Oldesthouse(dateConstruct, dateRebuild)

%write your code below

end

Code to call your function

dateConstructBig = [ 2070,2026,2062,2063,2021,2015,2062,2006,2037,2037,2064,2056,2026,2026];

dateRebuildBig= [3007,3002,2090,3000,2098,Nan, 2089,Nan,2081,2097,2099,2083,2083];

[Numb] = Oldesthouse(dateConstructBig, dateRebuildBig)

disp("oldest house location is:" + Numb)

Answer 1

function [Numb] = Oldesthouse(dateConstruct, dateRebuild)
dateRebuild(isnan(dateRebuild))=dateConstruct(isnan(dateRebuild));
oldest=dateRebuild(1);
for i=1:length(dateConstruct)
if dateRebuild(i)<oldest
oldest=dateRebuild(i);
end
end
indices=1:length(dateConstruct);
Numb=indices(dateRebuild==oldest);
end
