Test inputs write a function called checkinputs which checks if three inputs parameters are the correct data types. the first, second, and third input variables must be a string, numeric, and logical data type, respectively. the output of checkinputs should be a logical row array, errorcode, with 4 values.

Here you go,

Program:

function errorCode = CheckInputs (name, gpa, enrollStatus)

%Create a errorCode as a 1x4 logical array

errorCode=[true true true false];

%Check number input arguments taken by the function

%If the number of arguments are less than 3, assign the

%4th array element in errorCode to true

if nargin<3

errorCode (4) = true;

errorCode (3) = false;

errorCode (2) = false;

errorCode (1) = false;

%Otherwise (if there are three parameters),

else

%Check whether the first parameter is a string are not

%and set the first array element with true, if the

%first argument is string

if ischar (name)

errorCode (1) = ~ (ischar (name));

end

%Check whether the second parameter is a numeric value are not

%and set the second array element with true, if the

%second argument is a numeric value

if isnumeric (gpa)

errorCode (2) = ~ (isnumeric (gpa));

end

%Check whether the third parameter is a logical value are not

%and set the third array element with true, if the

%third argument is a logical value false

if islogical (enrollStatus)

errorCode (3) = ~ (islogical (enrollStatus));

end

end

end
