Hi
I am trying to obtain the coefficients of a polynomial (1+x)^i, where i varies from 1 to N.
The final result should concatenate the coefficients of all polynomials and produce resultant vector in powers of x.
Eg. (1+x)^2 = [(1 1) (1 2 1)] = [(x+1) (x^2 + 2x +1)]
I have tried writing the MATALB code as follows:
function y = eg10(N)a = zeros(1,N)y = zeros(1,N)b = zeros(1,N)p = [ 1 1]syms xq = poly2sym(p,x)for i = 1:N y(1,i) = q^i; a(1,i) = coeffs(y(1,i)) b(1,i) = poly2sym(a(1,i),x) c(1,i) = horzcat(b(1,i))end
But I am getting error as follows:
The following error occurred converting from sym to double:
DOUBLE cannot convert the input expression into a double array.
Error in eg10 (line 9)
y(1,i) = q^i;
Can anyone kindly suggest any possible solution to this?
