The Matrix Calculator performs the matrix operations supported by the tool, including addition, subtraction, multiplication, and scalar operations where available.
Dimension rules
Addition and subtraction require matrices with matching rows and columns. Matrix multiplication requires the number of columns in the first matrix to equal the number of rows in the second. Invalid matrices and unsupported operators return errors.
Example
For A = [[1, 2], [3, 4]] and B = [[5, 6], [7, 8]], A + B = [[6, 8], [10, 12]].
Questions
Can I multiply any two matrices?
No. The inner dimensions must match.
Does this calculate determinants or inverses?
Only if the selected operator and component expose those operations. Check the visible controls.
Are decimals supported?
The parser accepts numeric matrix values; display precision depends on the component.
Limitations
This is a browser matrix utility, not a computer-algebra system. It does not solve symbolic variables or guarantee arbitrary-precision output.
