Hi,

I wonder can anyone tell me why I get the error message:

>>>>>>> Error message <<<<<<
Error using ==> sym.maple
Error, integer too large in context

Error in ==> sym.double at 23
ValueOfS = str2num(map2mat(char(maple('evalf',S(:),d))));

Error in ==> n1th_deriv at 63
gx_6(:,idx) = double(gx6);

>>>>

when I try to run the function below.In the function xx is a vector
of length 16384 and maximum value 3.1413.

function gx = n1th_deriv(xx)
% wm = 2*pi*fm = 2*pi*5000
% xx = wm * (t - (0.5*Ts))

% Find the symbolic expression for the 6th order %
derivative of |cos(x)|^7
g6 = diff('(abs(cos(x)))^7','x',6);

for n = 1:1:length(xx)
% Assign x with a numeric value from the vector xx
x = xx(:,n);

% Substitute for x in the symbolic expressions
gx6 = subs(g6);

% Find the numeric value of the symbolic expression
gx_6(:,idx) = double(gx6);

end

% Return result
gx = gx_6;

Thanks
