trnd

Student's t random numbers

Syntax

r = trnd(nu)
r = trnd(nu,m,n,...)
r = trnd(nu,[m,n,...])


Description

r = trnd(nu) generates random numbers from Student's t distribution with nu degrees of freedom. nu can be a vector, a matrix, or a multidimensional array. The size of r is equal to the size of nu.

r = trnd(nu,m,n,...) or r = trnd(nu,[m,n,...]) generates an m-by-n-by-... array. The nu parameter can be a scalar or an array of the same size as r.

Examples

Generate Student's t Distribution Random Numbers

r1 = trnd(ones(1,6))

r1 = 1×6

    0.2108    7.8450  -11.0511    0.4134    4.3293   -0.8323

r2 = trnd(1:6,[1 6])

r2 = 1×6

    8.9290   -0.1908    0.3496   -0.7658    1.3234   -1.2808

r3 = trnd(3,2,6)

r3 = 2×6

    1.3157    0.7010    0.1591   -1.3840    4.1354    0.2442
    0.9789   -2.4700   -1.8884   -0.0116   -0.9496   -0.2340

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using MATLAB® Coder™.

Usage notes and limitations:

The generated code can return a different sequence of numbers than MATLAB^® if either of the following is true:

• The output is nonscalar.

• An input parameter is invalid for the distribution.
