Matrix calculator (original) (raw)

With help of this calculator you can: find the matrix determinant, the rank, raise the matrix to a power, find the sum and the multiplication of matrices, calculate the inverse matrix. Just type matrix elements and click the button.

• Leave extra cells empty to enter non-square matrices.
• You can use decimal fractions or mathematical expressions:
  • decimal (finite and periodic) fractions:
    1/3, 3.14, -1.3(56), or 1.2e-4
  • 2/3+3*(10-4), (1+x)/y^2, 2^0.5 (=2), 2^(1/3), 2^n, sin(phi), cos(3.142rad), a_1, or (root of x^5-x-1 near 1.2)
  • matrix literals:
    {{1,3},{4,5}}
  • operators:
    +, -, *, /, \, !, ^, ^{*}, ,, ;, ≠, =, ⩾, ⩽, >, and <
  • functions:
    sqrt, cbrt, exp, log, abs, conjugate, arg, min, max, gcd, rank, adjugate, inverse, determinant, transpose, pseudoinverse, trace, cos, sin, tan, cot, cosh, sinh, tanh, coth, arccos, arcsin, arctan, arccot, arcosh, arsinh, artanh, arcoth, derivative, factor, and resultant
  • units:
    rad, deg
  • special symbols:
    * pi, e, i — mathematical constants
    * k, n — integers
    * I or E — identity matrix
    * X, Y — matrix symbols
• Use ↵ Enter, Space, ←↑↓→, Backspace, and Delete to navigate between cells, Ctrl⌘ Cmd+C/Ctrl⌘ Cmd+V to copy/paste matrices.
• Drag-and-drop matrices from the results, or even from/to a text editor.
• To learn more about matrices use Wikipedia.

Examples

• {{11,3},{7,11}}*{{8,0,1},{0,3,5}}
• determinant({{1,2,3},{4,5,6},{7,2,9}})
• {{1,2},{3,4}}^-1
• {{1,2,3},{4,5,6},{7,2,9}}^-1
