modulo

Purpose

Computes the remainder after division (modulo operation).

Format

y = a % b

Parameters

param a:

Dividend.

type a:

scalar, vector, or matrix

param b:

Divisor.

type b:

scalar, vector, or matrix

Returns

return y:

Remainder of a divided by b.

rtype y:

matrix

Examples

y = 17 % 5;

y =    2.0000000

x = { 10, 11, 12, 13, 14, 15 };
y = x % 3;

y =    1.0000000
       2.0000000
       0.0000000
       1.0000000
       2.0000000
       0.0000000

Check for Even/Odd

x = { 1, 2, 3, 4, 5, 6 };
is_even = (x % 2) .== 0;

is_even =    0.0000000
             1.0000000
             0.0000000
             1.0000000
             0.0000000
             1.0000000

Remarks

• The result has the same sign as the dividend a.

• Both operands can be matrices of conformable dimensions.

• Equivalent to a - floor(a/b) * b.
