How to present the content of a field in a program?

I want to present the variables and their value from a structure in a program, just for information for the users.

Let's say:

a.a=234.5;
a.b=444;
a.s='This is an example';
a

if I run this code in the command window, I get the answer:

a =

struct with fields:

a: 234.5

b: 444

s: 'This is an example'

I want to reproduce this answer and put it in a text window in my program. I could not figure out how to do that.

Thanks for any help!

Try this:

a.a=234.5;
a.b=444;
a.s='This is an example';
a

a = struct with fields:
    a: 234.5000
    b: 444
    s: 'This is an example'

fn = fieldnames(a)

fn = 3×1 cell array
    {'a'}
    {'b'}
    {'s'}

str = sprintf('a = \nstruct with fields:');
for k = 1 : numel(fn)
	thisFieldName = fn{k};
	if ischar(a.(thisFieldName))
		% Print using %s
		str = sprintf("%s\n\t%s: '%s'", str, thisFieldName, a.(thisFieldName));
	else
		% Print using %g
		str = sprintf("%s\n\t%s: %g", str, thisFieldName, a.(thisFieldName));
	end
end
str % Display in command window.

str = 
    "a = 
     struct with fields:
     	a: 234.5
     	b: 444
     	s: 'This is an example'"
