How to use Matrix Calculator
- Load the included example or provide your own input and settings.
- Choose the operation and review the supported format below.
- Run the tool, inspect the result, and copy or download it.
Provide matrices as JSON arrays
Write each matrix as an outer array of row arrays. Every row must contain the same number of finite numeric cells. The first editor supplies matrix A; the second supplies matrix B when multiplying. Transposition exchanges rows and columns. Multiplication requires the number of columns in A to equal the number of rows in B, and returns the resulting rectangular matrix.
Interpret numerical determinants carefully
A determinant requires a square matrix and is calculated with row pivoting and elimination. Row swaps change the sign, and an exact zero pivot produces a zero determinant. These operations use floating-point numbers, so nearly singular matrices can accumulate rounding error. Dimensions are limited to ten by ten, extreme magnitudes are bounded, and overflowing results are rejected. This is a numerical helper rather than a symbolic algebra system.
