You can also use this matrix calculator as a multi-variable function evaluator. For example, inv(2) is treated as inv() which will be given as 0.5. Conversely, whenever appropriate, scalars are treated as 1 × 1 matrices. Also if, for example, A =, then sin( A) is treated as sin( 1/2). They can be multiplied by any matrix (on either side) regardless of its dimension. You can use the following in your expressions: inv(),Īll 1 × 1 matrices are treated as scalars by this matrix calculator. If the matrix expression is a valid expression and contains no operations of incompatible matrices, the result will be displayed. This matrix expression calculator allows you to use any matrix expression which can be in the most general form, such as (2+sin(π/3)) A + inv( A+ B/det( A))( B/2 + B C^4)/ D^(3+2^5) Press the Calculate button to evaluate it. If a matrix expression is not listed under the quick calculation menu, you can enter it in the expression box provided. Under the Quick Calculations drop-down-list you can calculate frequently used matrix expressions involving two or more matrices such as A + B, (A+B)(C+D), and many more. , H by first selecting them from the drop-down list and setting its dimensions and entries. You can do similarly as above with other matrices A, B, C. To calculate the determinant, inverse, reduced row echelon form, adjugate, rank, lower/upper triangular forms and transpose of a selected matrix ( A is initially selected) press the relevant buttons at the top of the matrix calculator. You can clear or fill a selected matrix by random numbers (integers between -10 and 10) by pressing the buttons provided. To clear the data and reset matrix calculator type in reset in the matrix expression box at the bottom of the matrix entries and press Clear, or clear site data from your browser history. This matrix calculator remembers the dimensions and entries of all matrices that you enter and also remembers whether a matrix is augmented for solving systems of linear equations.Īll the data are retained when you close the matrix calculator. With this matrix calculator you can use any numeric (constant) expression, e.g., 1/2+3sin(5π/4)i for a matrix enyries. You can then set its dimensions and fill the matrix with numbers ( real numbers, imaginary numbers or, in general, complex numbers) or expressions containing them. These matrices are initially filled with 0's, except for the matrix A. , H by first choosing it from the drop-down list on the right of the matrix calculator. You can select and/or modify a matrix A, B, C. You can also set the dimensions of a selected matrix by entering the number of its rows or columns in the text boxes provided. You can also conveniently set the number of rows or columns of a selected matrix by pressing the numbered buttons on the left of a row or above a column, respectively. You can increase the dimensions of a selected matrix by adding rows or columns to it by pressing the + ( insert row or insert column) buttons provided. In addition, solve systems of linear equations with real or complex coefficients and real or complex column vectors. Also calculate determinant, inverse, adjugate, rank, rref, and triangular forms of m × m matrices with real or complex entries. The matix calculator & linear system solver is for performing matrix algebra ( addition, subtraction, multiplication, inverses, etc.) of complex matrices. This augmented matrix calculator works seamlessly with linear systems of equations and solves linear systems with augmented matrices which can be complex matrices too. Moreover, for ' m by m' square matrices like 2x2, 3x3, 4x4 matrices you can use this matrix solver to calculateĪdditionally, compute matrix rank, matrix reduced row echelon form, upper & lower triangular forms and transpose of any matrix. A matrix with a complex entry is called a complex matrix.Īpart from matrix addition, matrix subtraction and matrix multiplication, you can use this complex matrix calculator to perform matrix algebra by evaluating matrix expressions like A + ABC - inv(D), where matrices can be of any compatible ' mxn' size. This matrix calculator is capable of performing matrix operations with matrices that any of their entries can be real, imaginary, or in general, a complex number.
