Frequently Asked Questions
When can I multiply matrices?▾
Matrix multiplication A×B requires that A's column count equals B's row count. The result has A's rows and B's columns.
What is a determinant?▾
The determinant is a scalar value computed from a square matrix. It indicates whether the matrix is invertible (det ≠ 0) and has geometric meaning related to scaling.
