Create matlab code from a variable

| Watch this File

File Information

matcode = SERIALIZE(x) generates matlab code of x
matcode = SERIALIZE(x, n) generates matlab code of x retaining n digits
of precision

SERIALIZE should be able to create matlab code of the following data types:
- matrices, vectors, and scalars of any class and dimension
- strings
- structs, arrays of structs with up to six dimensions
- cell arrays
- matlab objects with a copy constructor implemented
- empty values of any class
- any combinations hereof

The value of x can be obtained by

  x = [1 2 3; 3 4 5];
  x = uint8(rand(10)*5);
  matcode = serialize(x)

  x = {rand(3,3,3,4), 'a string value', {1 2 3; 1 3 3 }}
  matcode = serialize(x, 30)

As Sebastian already said, empty structures need to be fixed.

I suggest you to substitute the code in line 134:
val = 'struct(';

with the following one:
if numel(fieldNames) == 0
val = 'struct';
val = 'struct(';

Empty structures are not handled correctly:
>> serialize(struct)
ans = 'struc);'

It would be nice if it also serialized function handles - the following changes would do the trick.

elseif isa(v, 'function_handle')
val = serializehandle(v);

function val = serializehandle(v)
val = sprintf('str2func(''%s'')', func2str(v));

This is fantastic - exactly what I was looking for. Thanks

It's too bad it doesn't work for matlab 6.5 :(

An absolutely wonderful piece of code. I wish I now had the ability to read the output into software like excel.

Nice. Thanks for the quick update. I can see using this with building xml strings.

This has been fixed by converting such strings to uint8. Thanks for noticing me.

x{1} = 'rick''s'

y = serialize(x)

z = eval(y) %gives ??? Error: Unexpected MATLAB expression.
