Riemann Zeta function.
Syntax
Y = zeta(X)
Y = zeta(n, X)
Description
zeta(X) evaluates the Zeta function at the elements of X, a numeric matrix, or a symbolic matrix. The Zeta function is defined by
zeta(n, X) returns the n-th derivative of zeta(X).
Examples
zeta(1.5) returns 2.6124.
zeta(1.2:0.1:2.1) returns
Columns 1 through 7
5.5916 3.9319 3.1055 2.6124 2.2858 2.0543 1.8822
Columns 8 through 10
1.7497 1.6449 1.5602
zeta([x 2;4 x+y]) returns
[ zeta(x), 1/6*pi^2]
[ 1/90*pi^4, zeta(x+y)]
diff(zeta(x),x,3) returns zeta(3,x).
