Arguments

n

real or polynomial 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)
modulo(10, -4)

pmodulo(-3, 9)
pmodulo(10, -6)
pmodulo(-10, -6)
