So I have this code:(adsbygoogle = window.adsbygoogle || []).push({});

Basically, it's a three-point formula for approximating a derivative, where the variables n = the number of iterations, x = the input value for the sin function, i = iteration number, approx=the approximation of the derivative, and error = the difference between the actual derivative and the approximation.Code (Text):

function ApproxSinDeriv(x,n)

h=.5;

for i = 0:n

h;

approx = (1/(2*h))*(sin(x+h)-sin(x-h));

error = abs(approx-cos(x));

h = h/2;

A=[i,h,approx,error]

end

I put A equal to a matrix of these values, but the output comes out in 30 clunky, individual, one-row matrices.

How would I go about putting this data in an array? That is, one nice clean matrix with 30 rows and 4 columns [i,h,approx,error]?

Thanks!
