Question

answer in matlab please

Create a separate function file fieldtovar.m that receives a single structure as an input and assigns each of the field values to user-defined variables. The function should work for a structure with any number of fields. Additionally, implement an error check to ensure that the number of user- defined variables (output arguments) is equal to the number of structure fields. Here are two examples of calling the function: » Boeing_747 = struct('Length', 70.6, WingSpan', 64.4, 'Engine', "GE CF6"); » I ws eng) = fieldtovar(Boeing_747) 70.6000 ws = 64.4000 eng = "GE CF6" Boeing_747 = struct('Length', 70.6,'WingSpan', 64.4, 'Engine', "GE CF6"); » (I ws) = fieldtovar(Boeing_747) Error using fieldtovar (line XX) The number of output variables does not equal the number of fields. HINT: Consider using the built-in function fieldnames as well as a dynamic structure reference: structurename.( )

Answer 1

function [I ws eng] = fieldtovar(Boeing_747)
if numel(fieldnames(Boeing_747)) ==nargout('fieldtovar')
I = Boeing_747.Length;
ws = Boeing_747.WingSpan;
eng = Boeing_747.Engine;
else
disp("Error using fieldtovar \n The number of output variable does not equal to the number of field")
end
end

Boeing_747 = struct('Length',70.6, 'WingSpan', 64.4 , 'Engine',"CE CF6");
[I ws eng] = fieldtovar(Boeing_747)
