Hello,

My question is the following: How to assign a structure with fields (incl the values in the fields) as an output in function?

Let's say the code is something like this

function output =example(x)

struct(1).field1=x+1

struct(2).field1=x+2

struct(1).field2=x/5

struct(2).field2=x/6

output=struct(1:2)

_________________

How do I assign the fields with their values to the output variable. In this example here I have two fields, but in the actual function I have a lot more and all of these fields have values which I would like to use later in the workspace.

Any ideas?

do not use a keyword or function name ( _ struct_) as a variable name. You can easily avoid this using a variable name like MyStruct.

Sorry for the confusion - in the actual script I am not using the keywords. My structure and fields have names different from keywords.

Do you have any idea how to solve the issue with getting the whole structure with its fields and values as an output?

在 MATLAB Online 中打开

function Sout = myfunction(x)
S(1).field(1) = x ;
S(2).field(2) = 2*x ;
% etc.
Sout = S ; % just copy
% end of my function

Do not use names like field1, field2, but use an array (of doubles, cells or even structs)!!!

well done! Field names like Name and Credit are good names, of course.

@lou: you don't even need to make it that complicated. Simply put the name of the structure as the output argument, without assigning it to another variable:

 function S = myFun()
 S.name = ...
 S.age = ...
 end

It is not required to do output = S; anywhere.
