Dear all,
I want to use series() in MATLAB. http://de.mathworks.com/help/symbolic/mupad_ref/series.html In MuPAD it works:
s := series(sin(x), x)
gives me:
x - x^3/6 + x^5/120 + O(x^7)
In MATLAB I use:
syms x
s = feval(symengine,'series',sin(x), x)
but this gives me:
Series::Puiseux::create(1, 1, 7, [1, 0, -1/6, 0, 1/120], x, 0, Undirected)
What can I do to get:
x - x^3/6 + x^5/120 + O(x^7)
instead?
Thanks and best regards

Btw.:
z = feval(symengine,'mtaylor',sin(x), x)
Works fine but I dont want to use the Taylor series.

f = matlabFunction(s)
I'm kind of surprised that formula(s) doesn't return what you have above. It might be worth contacting tech support on that. The information is clearly there as matlabFunction or pretty show.

Thank you for your answer. The command matlabFunction(s) does already help me but I also contacted the support as you indicated.
