Question

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 userdefined variables (output arguments) is equal to the number of structure fields.

Answer 1

Explanation gives the answer

Step-by-step explanation:

% Using MATLAB,

% Matlab file : fieldtovar.m

function varargout = fieldtovar(S)

% function that accepts single structure as input, assigning each

% of the field values to user-defined variables

fields = fieldnames(S); % get the field names of the input structure

% check if number of user-defined variables and number of fields in

% structure are equal

if nargout == length(fields)

% if equal assign each value of structure to user-defined varable

for i=1:nargout

varargout{i} = getfield(S,fields{i});

end

else

% if not equal display an error message

error('The number of output variables does not equal the number of fields');

end

end

%This brings an end to the program
