— Function File: x = raylrnd (sigma)
— Function File: x = raylrnd (sigma, sz)
— Function File: x = raylrnd (sigma, r, c)

Generate a matrix of random samples from the Rayleigh distribution.

Arguments

• sigma is the parameter of the Rayleigh distribution. The elements of sigma must be positive.
• sz is the size of the matrix to be generated. sz must be a vector of non-negative integers.
• r is the number of rows of the matrix to be generated. r must be a non-negative integer.
• c is the number of columns of the matrix to be generated. c must be a non-negative integer.

Return values

• x is a matrix of random samples from the Rayleigh distribution with corresponding parameter sigma. If neither sz nor r and c are specified, then x is of the same size as sigma.

Examples

          sigma = 1:6;
          x = raylrnd (sigma)
          
          sz = [2, 3];
          x = raylrnd (0.5, sz)
          
          r = 2;
          c = 3;
          x = raylrnd (0.5, r, c)
