addition

Purpose

Adds two matrices, vectors, or scalars element-by-element.

Format

y = a + b

Parameters

param a:

Left operand.

type a:

matrix, vector, or scalar

param b:

Right operand.

type b:

matrix, vector, or scalar

Returns

return y:

Element-by-element sum of a and b.

rtype y:

matrix

Examples

a = { 1, 2, 3 };
b = { 10, 20, 30 };
y = a + b;

y =   11.0000000
      22.0000000
      33.0000000

Scalar Addition

x = { 1, 2, 3 };
y = x + 10;

y =   11.0000000
      12.0000000
      13.0000000

Remarks

• If both operands are matrices, they must be conformable (same dimensions) or one must be a scalar.

• Scalar operands are broadcast to match the dimensions of the matrix operand.
