Question

Create a vector of structures experiments that stores information on subjects used in an experiment. Each struct has four fields: ID, name, weights, and height. The field ID is an integer, name is a string, weights are a vector with two values in pounds (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.
Experiments
ID Name Weights Height (feet) Icnhes
1 2
1 1111 Bob 150.1 149.6 6 1
2 2222 Ann 106.2 106.6 5 3

Write a function printhheight that will receive a vector of structures in this format and will print the name, ID and height of each subject in inches (1 foot = 12 inches). This function calls another function height that receives a height struct and returns the total height in inches. This function could also be called separately.

Answer 1

Answer:

im assuming this is required to be done in matlabs.

Explanation:

experiment.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('ID', 2222); 'name'; 'Ann'; ...  

   'weights'; '106.2, 106.6.9'; 'height'; struct('feet',5, 'inches',3);

experiments(1) = struct('ID',1111);'name'; 'Bob'; ...  

'weights'; '150.1, 149.6'; 'height'; ...

struct('feet', 6, 'inches', 1);

printhheight(experiments)

printhheight.m

function printhheight(experiments)

% Prints height of every subject

% Format of call: prinths(experiments vector)

% Does not return any values

for i = 1 : length(experiments), high = height(experiments(i)*height);

fprintf('%s is %d inches tall\n', ...

     experiments(i).name, high)

end

end

height.m

function ht = height(expstruct)

% Calculates height in inches of a subject

% Format of call: height(experiment struct)

% Returns height in inches

ht = expstruct.feet*12+expstruct.inches;

end
