min(
matrix1, matrix2

matrix
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.
min(2.3,1.4) ¸ 1.4
min({1,2},{
ë 4,3}) ¸ {ë4 2}
min(
list
)
expression
Returns the minimum element of
list
.
min({0,1,ë 7,1.3,.5}) ¸ ë7
min(
matrix1
)
matrix
Returns a row vector containing the minimum
element of each column in
matrix1
.
Note: See also
fMin() and max().

list
mod(
matrix1
,
matrix2
)
matrix
Returns the first argument modulo the second
argument as defined by the identities:
mod(x,0) x
mod(x,y) xì 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.
