These sections explain the job in plain language and set expectations for what the tool should do well.
The Matrix Calculator lets you enter two matrices, set their rows and columns, and run linear-algebra operations instantly. Add, subtract, or multiply the two matrices, or pick one and get its transpose, determinant, or inverse. Every result is computed live in your browser using exact Gaussian elimination, so nothing is uploaded and there is no account or install. When shapes do not line up for multiplication, or a matrix has no inverse because its determinant is zero, the tool explains the problem instead of failing silently.
Short answers for the questions people usually have before trying a utility like this.
Yes. It runs entirely in your browser with no signup and no upload, so the numbers you enter never leave your device.
You can set each matrix from 1 x 1 up to 6 x 6 and adjust the rows and columns independently before running an operation.
A matrix can only be inverted when it is square and its determinant is not zero. If the determinant is zero the matrix is singular, so no inverse exists and the tool reports that instead of returning wrong numbers.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
