Examples

import mir.test: shouldApprox;

0.0.rayleighPDF.shouldApprox == 0.0;
0.5.rayleighPDF.shouldApprox == 0.4412485;
1.0.rayleighPDF.shouldApprox == 0.6065307;
2.0.rayleighPDF.shouldApprox == 0.2706706;

// Can also provide scale parameter
0.5.rayleighPDF(2.0).shouldApprox == 0.1211541;
1.0.rayleighPDF(2.0).shouldApprox == 0.2206242;
4.0.rayleighPDF(2.0).shouldApprox == 0.1353353;
