Alternatives for str2num function not supported for code generation

Hi All,

The following function `str2num` is not supported for code generation.

nodes  = str2num(char(G.Nodes.Name));  

The nodes names were assigned using the below

G = graph(tail,head);
G.Nodes.Name = cellstr(string(1:height(G.Nodes))');

Other instances where I'm using `str2num`

 t    = str2num(GraphEdges{edge}(1));
 h    = str2num(GraphEdges{edge}(2));

Suggestion on an alternate function to str2num that could be used for code generation will be really helpful.

STR2DOUBLE, SSCANF, etc... but which one to select depends largely on the data format.

Thank you for the suggestions.

str2double wors for t = str2num(GraphEdges{edge}(1));

However, I am not sure what has to be used for 'str2num(char(G.Nodes.Name))'

The output of G.Nodes.Name is

    {'1' }
    {'2' }
    {'3' }
    {'4' }
    {'5' }
    {'6' }
    {'7' }
    {'8' }
    {'9' }

    G.Nodes.Name=cellstr(num2str([1:9].'));   % make example struct
    N=str2double(G.Nodes.Name)                % convert to numeric

N = 9×1

1 2 3 4 5 6 7 8 9
