What matrix sizes are supported?

The calculator supports 2×2, 3×3, and 4×4 matrices for all operations. This covers the most common use cases in linear algebra and practical applications.

Can I perform operations between different sized matrices?

Matrix addition and subtraction require identical dimensions. Matrix multiplication requires the number of columns in the first matrix to equal the number of rows in the second matrix. Other operations like determinant and inverse require square matrices.

What precision do the calculations use?

All calculations are performed using standard JavaScript floating-point arithmetic with results displayed to 4 decimal places. While this provides sufficient precision for most applications, be aware that floating-point arithmetic can introduce small rounding errors.

Why do I get an error for determinant calculation?

Determinants can only be calculated for square matrices (2×2, 3×3, 4×4). Ensure your matrix has the same number of rows and columns before attempting determinant calculations.

What are the limitations of matrix inversion?

Matrix inversion requires a square matrix with a non-zero determinant (non-singular matrix). If the determinant is zero or very close to zero, the matrix cannot be inverted, and you will receive an appropriate error message.
