MATLAB: Only accept odd numbered input arguments

functionMATLABmatlab function

I am writing a function and I would like it to only run if the input argument is odd, is there an easy to specifcy that the input must be odd.

nargin counts the number of input arguments for a function.

mod(x,2) returns 1 when x is odd.

if mod(nargin,2)~=1
    error('There must be an odd number of inputs.')
end

MATLAB: Second output argument as input argument

There is no MATLAB syntax or built-in function that supports what you want to do, unfortunately.

MATLAB: Polyfit with odd powers only

x = [ ... ];
y = [ ... ];
x = x.';
y = y.';
  
n = 5;      % degree of polynomial p ; n must be odd
A = [];
for i = 1:2:n
  A = [A x.^i];
end
coeff = A\y  % Polynomial is given by p(z)=coeff(1)*z + coeff(2)*z^3 + ... + coeff((n+1)/2)*z^n
