laguerre_variance

Variance of Laguerre polynomials

Calling Sequence

y=laguerre_variance(n)

Parameters

n :

a 1-by-1 matrix of doubles, integer value, n>=0.

y :

a matrix of doubles, the variance

Description

Compute the variance

for n=0,1,2,..., where X is a standard exponential random variable.

Examples

for n=0:5
V=laguerre_variance(n);
mprintf("n=%d, V(Ln)=%f\n",n,V)
end
