What Is Matrix Scaling?

Scaling a matrix means multiplying every entry by the same scalar. The matrix keeps the same dimensions while each value grows or shrinks by the chosen factor.

How to Multiply a Matrix by a Scalar

  1. Enter a scalar value.
  2. Enter each matrix entry.
  3. Multiply every entry by the scalar.
  4. Read the scaled matrix in the result panel.
B = kA

Worked Example

2 × [[1, 2], [3, 4]] = [[2, 4], [6, 8]]

Frequently Asked Questions

Can the scalar be negative?

Yes. A negative scalar flips the sign of every entry in the matrix.

Does the matrix size change?

No. Scaling keeps the same number of rows and columns.

Can I enter decimals?

Yes. Any finite real scalar or matrix entry is accepted.

What if a cell is blank?

Blank cells are rejected instead of being silently converted to zero.
