Returns the minimum of the two arguments. If
the arguments are two lists or matrices, returns a
list or matrix containing the minimum value of
each pair of corresponding elements.

matrix
Returns the first argument modulo the second
argument as defined by the identities:
mod(x,0)  x
mod(x,y)  x ì y floor(x/y)
When the second argument is non-zero, the result
is periodic in that argument. The result is either
zero or has the same sign as the second
argument.
If the arguments are two lists or two matrices,
returns a list or matrix containing the modulo of
each pair of corresponding elements.
