Questions

Multiply Matrices FAQ

Can I multiply matrices of any size?
No, the inner dimensions must match (columns of first matrix = rows of second matrix). If A is m×n and B is p×q, then n must equal the inner dimension, and the result will be m×n dimensions.
Can I multiply any two matrices?
No. The number of columns in the first matrix must equal the number of rows in the second matrix. If A is m×n and B is p×q, then n must equal m for multiplication to be defined.
Can I multiply any two matrices together?
No. The number of columns in the first matrix must equal the number of rows in the second matrix. If A is m×n and B is p×q, then n must equal m for multiplication to be defined.
