Matrix elements 2 -1 0 -1 3 5 0 5 -2

 Matrix form of record of this square form

The calculation of the quadratic form is a fairly simple task, at least the descriptive part is primitive to impossibility and the calculation algorithm, when the matrix is ​​known, consists in calculating each of the elements according to the formula

Where,  - matrix element

But everything is primitive, does not mean convenient, and it is easy to make mistakes when calculating a quadratic form. Our calculator will help you not to make mistakes in the calculations.

As with all calculators, a matrix can contain not only real numbers, but also complex ones.

When entering data, we have two fields:

the first is the matrix;

the second is a way to name each element.

If in the second field we write some sort of character (a, b, c ....) then each element will be named

Let's look at a few examples.

Enter the elements of the matrix with a space (you can start each row with a new line)

and get the following results

Complex field calculation

Good calculations !!
