| Description |
TDIST Computes the distribution of a linear combination of independent Student's T random variables (with small degrees of freedom, df<=100)and/or standard Normal Z random variables.
Syntax: [yfun,xfun,iserr] = tdist(funx,df,lambda,funtype,points)
EXAMPLE 1.
Plot the PDF of a linear combination of independent Student's T random variables with 1, 2, 3, and 4 degrees of freedom and with independent standard Normal random variable.
The coefficients of the linear combination are given by lambda=[1 2 3 4 5].
funx=[];
df=[1 2 3 4 Inf];
lambda=[1 2 3 4 5];
FunType=2;
GaussQuadPoints=6;
[yfun,xfun,iserr] = tdist(funx,df,lambda,FunType,GaussQuadPoints);
plot(xfun,yfun);
