Could anyone help me to solve the issue in the command line

feval(symengine, 'combinat::bell', 4) I can run the command line with respect to 4.Could anyone help how to run the same command with respect to different numbers 12,24,36 instead of 4 in such a way the command needs to take the numbers in order.

 for i = [4, 12, 24, 36]
     feval(symengine,'combinat::bell',i);
 end

Is this what you looking for?

Or,

arrayfun(@(i) feval(symengine, 'combinat::bell', i), [4 12 24 36])

[Ji Hoon Jeong]

Wow didn't know that one. Thanks!

[jaah navi]

when i use the command arrayfun(@(i) feval(symengine, 'combinat::bell', i), [4 12 24 36]) i am getting error stating Error using arrayfun sym output type is not supported. Set 'UniformOutput' to false.Could you please help me on this.

In my environment(2018a Update 5), Walter's code works fine. arrayfun in an older version of the Matlab may not not support sym output

[Walter Roberson]

temp =  arrayfun(@(i) feval(symengine, 'combinat::bell', i), [4 12 24 36], 'uniform', 0);
output = vertcat(temp{:});

[jaah navi]

Thanks.It works.

[jaah navi]

For the code

   temp =  arrayfun(@(i) feval(symengine, 'combinat::bell', i), [4 5 6], 'uniform', 0);
  output = vertcat(temp{:});

I am getting the result as output =

    15
    52
   203.

Could you please help me how to get what are the partitions present in those outputs 15,52,203 with respect to their corresponding numbers.
