(*) multiply operator
(number * number) 🡒 number, const autodiff
The regular multiplication of two numbers.
x = 3
y = 2
show scalar "" with x * y
(ranvar * ranvar) 🡒 ranvar
The multiplication of two random independent variables over $\mathbb{Z}$.
x1 = poisson(5)
x2 = poisson(3)
show scalar "" a1b2 with x1 * x2
This operation is also known as the Dirichlet convolution. Under the hood, a convolution happens. The mean of the resulting ranvar is equal to the product of the means of the two ranvar operands.
(zedfunc * zedfunc) 🡒 zedfunc
The multiplication of two zedfuncs, real functions over $\mathbb{Z}$..
Example:
f = linear(3)
g = linear(2)
show scalar "" a1b2 with f * g
(text * number) 🡒 number
Repeats text a specified number of times. "ABC" * 3 is "ABCABCABC". An integer is expected.
Example:
show scalar "" a1c1 with "ABC" * 3
