Appendix A: Functions and Instructions

min()

MATH/List menu

min(

expression1

,

expression2

)

expression

min(

list1, list2

)

list

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},{л 4,3})

¸

{л 4 2}

min(

list

)

expression

Returns the minimum element of

list

.

min({0,1,л 7,1.3,.5})

¸

л

min(

matrix1

)

matrix

Returns a row vector containing the minimum
element of each column in

matrix1

.

Note: See also

fMin()

and

max()

.

min([1,л 3,7;л 4,0,.3])

mod()

MATH/Number menu

mod(

expression1

,

expression2

)

expression

mod(

list1

,

list2

)

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.
