MATLAB: Name-value pairs

name-value pairparsing the inputs of a function

Can anyone point out the solution to the error shown below (in the end)?
Thank you in advance.
function output = name_value_pairs(varargin)
if nargin == 0 || rem(length(varargin),2) ~= 0
    output = {};
    return;
end
for i = 1:length(varargin)
    if ~ischar(varargin{i})
        if ~isdouble(varargin{i}) || isfloat(varargin{i}) 
            output = {};
            return;
        end 
    end
end
output = cell(((length(varargin))/2),2);
n =1 ;
for j = 1: (length(varargin))/2
    for k = 1:2
        output{j,k} = varargin{n};
        n = n+1;
    end
end
end

Best Answer

You can use reshape
function C = name_value_pairs(varargin)
    if nargin == 0 || rem(numel(varargin),2) ~= 0
        C = {};
        return;
    end
    
    C = reshape(varargin, 2, []).';
    if ~all(cellfun(@ischar, C))
        C = {}
    end
end
