Cell ConvertTypes - size inputs must be scalar????

Why does cell ConvertTypes not work for this?

K>> whos co

Name      Size            Bytes  Class              Attributes

co        1x1               112  System.Double[]

K>> c2 = cell(co, 'ConvertTypes', 'all')

Error using cell
Size inputs must be scalar.

"Why does cell ConvertTypes not work for this?"

The question is rather why do you expect it to work? Nowhere does it say in the documentation of cell that it takes optional paramater-names 'ConvertTypes', 'all' (or any optional parameter for that matter). As a result, your strings are interpreted as size arguments.

In any case, to convert a .Net array of doubles into a matlab array of double, it's simply:

c2 = double(co)

This was the article that led me to believe it would work:

See the matlab 2016 (implemented in 2015b) article on convert .NET object arrays to cell arrays:

http://www.mathworks.com/help/matlab/matlab_external/net-arrays-to-cell-arrays.html

The reason I tried that was that I was getting a problem with

K>> cell(c)

Error using cell
Conversion to cell from System.Double[] is not possible.

Oh. I wonder why it does not appear in the documentation of cell (Although it's linked from there and I missed it).

Anyway, as I said, use

double(co)

to extract your array. If you then really want a cell array:

num2cell(double(co))
