Question

hi i'm a 1st year engineering student. and there is this problem which i cant to at all.. can someone help me out.. or atleast start me off in the right direction this is the question Any function can be expanded as a power series, a fact that is widely used in numerical analysis. For example the exponential function can be expected to give e^x = 1 + x + x^2/2! + x^3/3! + x^4/4! + ..... using a for loop. write a matlab program that computes approximations to e^x using the 1st n terms of the power series expansion. THe values of x and n should be fed in from the keyboard. can someone help m

Answer 1

prompt the user of x and n using something like:
n=input('n=')

the for loop should look like
for k=1:n
your series statement with n and x variables
end

Answer 2

is this from a specific matlab book? Is the Gilat one? If so, and you know what number question it is, I can give you the answer

Answer 3

no its an assignment ,, i dont know which book

Answer 4

Hello My Dear Friend, @sab11 WelcoMe To OpeN studY !!

I'm not a professional in Matlab, why not have a look at http://www.mathworks.in/matlabcentral/newsreader/view_thread/53134 , Does this helps ?

Hope, if U Are Satisfied with this answer, Please Close This Question !

Answer 5

Hmm... I just gave a Try !

function e = evaluation(x,n)
e = 0;
for k = 0:n
e = e + x^k/factorial(k);
end
end

Also,
x=input('Enter x: ');
n=input('Enter n: ');
e = 0;
for k = 0:n
e = e + x^k/factorial(k);
end
end

It prompts for x and n and then display the result.
please Check it, i too got confused while recalculating !
