MATLAB: Undefined function ‘chi’ for input arguments of type ‘double’.

type 'double'

I am calculating zeroth order Bessel root function using function 'chi'. This yielded me the roots successfully for the range I had asked for. Now today when I m running the same code, 'Undefined function 'chi' for input arguments of type 'double' has been displayed. one day this function is acceptable and the next day it is not. I m unable to understand this.Anybody please help.

chi is not a Mathworks function, and does not appear to be part of any File Exchange contribution either.

MATLAB: Undefined function ‘Trapzoid’ for input arguments of type ‘double’.

Note:

x = a:h:b;
for i=1:N(j)+1
  y(i)=exp(x(i));
end

is less efficient than:

y = exp(a:h:b);
