The table below describes the Addition operator.

Table 1.
+ Scalar Row Vector Column Vector Matrix
Scalar Adds the two scalar values. Adds the scalar to each element in the row vector. The resulting vector is the same size as the original vector. Adds the scalar to each element in the column vector. The resulting vector is the same size as the original vector. Adds the scalar to each element in the matrix. The resulting vector is the same size as the original matrix.
Row Vector Adds the scalar to each element in the row vector. The resulting vector is the same size as the original vector. Requires vectors to be the same size. Adds each element in operand 1 to the corresponding element in operand 2. The resulting vector is the same size as the original vectors. Each row/column vector is implicitly replicated until the two arguments have the same dimensions. Regular matrix addition is then performed. The row vector is implicitly replicated until the two arguments have the same number of rows. Regular matrix addition is then performed.
Column Vector Adds the scalar to each element in the column vector. The resulting vector is the same size as the original vector. Each row/column is implicitly replicated until the two arguments have the same dimensions. Regular matrix addition is then performed. Requires vectors to be the same size. Adds each element in operand 1 to the corresponding element in operand 2. The resulting vector is the same size as the original vectors. The column vector is implicitly replicated until the two arguments have the same number of columns. Regular matrix addition is then performed.
Matrix Adds the scalar to each element in the matrix. The resulting vector is the same size as the original matrix. The row vector is implicitly replicated until the two arguments have the same number of rows. Regular matrix addition is then performed. The column vector is implicitly replicated until the two arguments have the same number of columns. Regular matrix addition is then performed. Requires matrices to be the same size. Adds each element in operand 1 to the corresponding element in operand 2. The resulting vector is the same size as the original matrices.

## Examples

1 + 1
ans = 2
3 + [2 5 2]
ans = [5 8 5]
[2 5; 6 2] + [8 3; 6 7]
ans = [10 8; 12 9]
Invalid examples:
[5 4 2] + [4 3]
