SIMPLEPDF is the jCommon module of jLab.

 SIMPLEPDF  Gaussian, uniform, Cauchy, and exponential pdfs.
 
    F=SIMPLEPDF(X,MU,SIG,'gaussian') computes a Gaussian pdf with mean
    MU and standard deviation SIG.
   
    F=SIMPLEPDF(X,MU,SIG,'boxcar') computes a uniform pdf with mean MU
    and standard deviation SIG.
   
    F=SIMPLEPDF(X,XO,ALPHA,'cauchy') computes a Cauchy pdf with location
    parameter XO and scale parameter ALPHA.
 
    F=SIMPLEPDF(X,BETA,'exponential') computes an exponential pdf with
    scale parameter, hence mean and standard deviation, equal to BETA.
 
    'simplepdf --f' generates a sample figure
 
    Usage: f=simplepdf(x,mu,sig,'gaussian');
           f=simplepdf(x,mu,sig,'boxcar');
           f=simplepdf(x,xo,alpha,'cauchy');
           f=simplepdf(x,beta,'exponential');
