Set mask parameter with a cell array using set_param

I would like to set a custom Simulink block's mask parameter with a cell array:

C = {'a', 'b'};
set_param(gcb, 'mask_parameter', C);

This fails because the third parameter to set_param() must be a string.

However, this works:

C1 = '{''a'', ''b''}';
set_param(gcb, 'mask_parameter', C1);

as well as

mx = [1,2,3];
set_param(gcb, 'mask_parameter', mat2str(mx));

How can I convert C to a string? I need something like cell2str(C).

Can anyone help please?

Here's a way to generate that C1 from that C

C = {'a', 'b'};

C1 = strrep(strtrim(char(formattedDisplayText(C))),'}    {',', ')

C1 = '{'a', 'b'}'

C1_given = '{''a'', ''b''}';

isequal(C1,C1_given)

ans = logical

Thank you very much. Unfortunately I am unsing R2018b :( so I don't have formattedDisplayText(), but none the less, I though I was missing a simple internal function call.

I had to implement it using mat2str(), because my cell matrix consisted of strings that may contain apostrophes.
