Matrix Calculator
https://www.calculator.net/matrix-calculator.htmlWhen multiplying two matrices, the resulting matrix will have the same number of rows as the first matrix, in this case A, and the same number of columns as the second matrix, B.Since A is 2 × 3 and B is 3 × 4, C will be a 2 × 4 matrix. The colors here can help determine first, whether two matrices can be multiplied, and second, the dimensions of the resulting matrix.

Costenoble at Hofstra University. It was developed in conjunction with their book Finite Mathematics Applied to the Real World. Use of this utility is quite intuitive.
Reduced Row Echelon Form (RREF) of a matrix calculator
planetcalc.com › 8328This online calculator reduces a given matrix to a Reduced Row Echelon Form (rref) or row canonical form, and shows the process step-by-step Not only does it reduce a given matrix into the Reduced Row Echelon Form, but it also shows the solution in terms of elementary row operations applied to the matrix.
