Name-Value Pairs error

I am trying to solve this question using "name_value_pairs" but it is accepting "wrong type for name", rest the code is running just fine ...

Can you please guide me what am i doing wrong!

The code i am using is given below!

function db = name_value_pairs(varargin)
d=0;
if (nargin == 0 || rem(length(varargin),2)~=0)
    d = cell (0,0);
else
    for i = 1:2:length(varargin)-1
        if ~ischar(varargin{i})
            d= cel(0,0);
            break
        end
    end
end
if isequal(d,cell(0,0))
    db = cell(0,0);
else
    db = reshape(varargin,2,length(varargin)/2)' ;
end
end

Make it easier for us to help you by

• providing some inputs that recreate the error

or

• sharing the entire error message
• tell us what line is causing the error

There is no error in code.

The only problem is that it is not checking if someone enter wrong type of data for name input.

[Adam Danz]

What is " name input"?

What type of data do you expect?

Is your question, "how do I validate the input values"?

Typo here

d= cel(0,0);
%  ^^^ should be "cell"

That typo solved the problem!

Thank you so much for the help :)

If you use inputParser, you can define validation functions
