![1. (10 pts) Write a function called hws_problem1 that accepts three input arguments: 1) a 3-column string matrix (say names), 2) a 4-column numeric matrix (say, numbers), and 3) a scalar threshold value (say, threshold). Note that the names matrix is the new string type that uses double quotes. The first two input arguments contain information about U.S. astronauts, where each corresponding row of the two matrices represents a single astronaut. The columns of the two matrices contain the following information for an astronaut: -First name: first column of names. - Middle name: second column of names. -Last name: third column of names. - Month of birth: first column of numbers. - Day of birth: second column of numbers. - Year of birth: third column of numbers. - Hours in space: fourth column of numbers. The function should return a struct array containing the information about astronauts whose hours in space exceed the given threshold (the third input argument). For example, given the following matrices for names and numbers, respectively: names Malcolm ScottCarpenter Leroy Gordon Cooper Jr.; JohnHerschel Glenn Jr.; VirgilIvan WalterMartySchirra 3r. Grissom numbers [5 1 1925 4; 3 6 1927 225; 7 18 1921 217; 4 3 1926 5; 3 12 1923 295 ]](http://img.homeworklib.com/questions/0e330400-b7c8-11ea-97ef-cd0e65434e1d.png?x-oss-process=image/resize,w_560)

% looping for each column
for indx = 1:numel(col)

Define an ordinary function called DisplayMin that has three parameters: the first two parameters are parallel arrays of different types and the third argument is of type size_t representing the size of both arrays. The function DisplayMin must work when called with various types of actual arguments, for example string DisplayMin(string names[], int calories[], int size) or int DisplayMin(int calories[], float prices[], int size). (Parallel Arrays are two arrays whose data is related by a common index. For example: with...
