Create a vector of structures experiments that stores information on subjects used in an experiment. Each struct has four fields: num, name, weights, and height. The field num is an integer, name is a string, weights is a vector with two values (both of which are double values), and height is a struct with fields feet and inches (both of which are integers). The following is an example of what the format might look like.
Write a function printhts that will receive a vector in this format and will print the name and height of each subject in inches (1 foot = 12 inches). This function calls another function howhigh that receives a height struct and returns the total height in inches. This function could also be called separately.

Ch8Ex26.m
% Create an "experiments" vector of structures
% variable, and pass it to a function that will
% print the height of each subject
experiments(2) = struct('num', 11, 'name', 'Sally', ...
'weights', [111.45, 111.11], 'height',...
struct('feet',7, 'inches',2));
experiments(1) = struct('num',33,'name', 'Joe', ...
'weights', [200.34 202.45], 'height', ...
struct('feet', 5, 'inches', 6));
prinths(experiments)
prinths.m
function prinths(exps)
% Prints height of every subject
% Format of call: prinths(experiments vector)
% Does not return any values
for i = 1: length(exps)
high = howhigh(exps(i).height);
fprintf('%s is %d inches tall\n', ...
exps(i).name, high)
end
end
howhigh.m
function ht = howhigh(expstruct)
% Calculates height in inches of a subject
% Format of call: howhigh(experiment struct)
% Returns height in inches
ht = expstruct.feet*12+expstruct.inches;
