variable number of input arguments

write a function called name_value_pairs that has variable number of input arguments representing name_value_pairs.Naturally,they come in pairs:the first is the name,the next is the value.This means that the function must be called with an even number of actual input arguments. The function returns a single cell array which has exactly two columns:first column contains the name,while the second column contains the values.If function is called with no input argument ,or it is called with an odd number of inputs or if a name is not of char type,the function return an empty cell array. here an example run:

>>db = name_value_pairs('name','john smith','age',32,'children',{'joe','jill'})
db =
   3*2 cell array
       {'name'}      {'john smith'}
       {'age'}       {[32]}
       {'children'}  {1*2 cell}

You can use varargin

function C = name_value_pairs(varargin)
    assert(mod(nargin, 2)==0, 'Number of input arguments must be even.');
    C = reshape(varargin, 2, []).';
end

Run it like this

db = name_value_pairs('name','john smith','age',32,'children',{'joe','jill'})

Result

>> db
db =
  3×2 cell array
    {'name'    }    {'john smith'}
    {'age'     }    {[        32]}
    {'children'}    {1×2 cell    }

thank you ,but could you solve it without assert .

[Ameer Hamza]

You can use if-block instead of assert line

if mod(nargin, 2)==1
    C = {};
    return;
end
