chebyshev_weight

Chebyshev weight function

Calling Sequence

y=chebyshev_weight(x)

Parameters

x :

a matrix of doubles

y :

a matrix of doubles, the weight

Description

Computes the Chebyshev weight function:

for x in (-1,1).

Examples

x=linspace(-0.99,0.99,1000);
y=chebyshev_weight(x);
scf();
plot(x,y)
xtitle("Chebyshev weight","x","w(x)")

v=intg(-1,1,chebyshev_weight)
sqrt(%pi)
