What it does
MatrixCalc works with matrices and equation systems, including determinants, inverses, rank and decompositions.
MatrixCalc accepts A and B matrices as cell entries or matrix literals, including fractions, repeating decimals, expressions and symbolic elements. Choose an operation such as determinant, inverse, rank, decomposition or A×B; leave extra cells blank for a rectangular matrix. Compatible dimensions and an operation's mathematical prerequisites still matter. Decimal display can specify fraction digits or significant digits. Keyboard navigation, matrix copy/paste and dragging results into a matrix or text editor help reuse working. Angle expressions can explicitly use rad or deg. The interface also has a separate system-of-equations route.
