modulo

symmetric arithmetic remainder modulo m

pmodulo

positive arithmetic remainder modulo m

Calling Sequence

i = modulo(n,m)

i = pmodulo(n,m)

Arguments

:n real vector or matrix : :m real vector or matrix :

Description

modulo computes i = n (modulo m) i.e. remainder of n divided by m ( n and m are integers).

i = n - m .* int (n ./ m). Here the answer may be negative if n or m are negative.

pmodulo computes i = n - m .* floor (n ./ m) ,the answer is positive or zero.

modulo(x,0) returns an error message: “Division by zero...”. With ieee(2), modulo(x,0) returns %nan.

pmodulo(x,0) returns an error message: “Division by zero...”. With ieee(2), pmodulo(x,0) returns %nan.

Examples

n=[1,2,10,15];m=[2,2,3,5];
`modulo`_(n,m)

`modulo`_(-3,9)
pmodulo(-3,9)
