Excellent Super util me ayudo mucho y lo mejor de todo es q me ahorro comprarme una calculadora costosa muchas gracias

Nexus 7 Does exactly what is says, the best matrix app ever

Bugged Even after I change the matrices and the operation, the app keeps reporting a previous answer.

does what it says kind of confusing ui in the beginning but perfect.

Listen Read Device Only Added Installed Matrix Calculator Free is an easy, fast and powerful tool for various matrix operations.

It provides one-click buttons for getting

• inverse

• determinant

• trace

• rank

• eigenvalues

• eigenvectors

• pseudo-inverse

Its advanced features extend to

• Eigendecomposition

• Cholesky decomposition

• QR decomposition

• LU decomposition

• Singular value decomposition

• Linear equation system solver

• Least square estimation in regression model

• Random matrix generator

Another nice feature is matrix computation of addition, subtraction and multiplication with up to 3 matrices. For this, Matrix Calculator Free provides intuitive user interface which enables you to do matrix computation with ease.

Matrix Calculator Free is a free trial version of Matrix Calculator Pro. The free version is limiting to handling matrices with dimensions less than 3. For the matrices bigger than 2 by 2, the result from various matrix operations including matrix inverse is partially shown.

If you like Matrix Calculator Free, please upgrade to the Pro version. Matrix Calculator Pro is so fast that inverse of 20 by 20 matrix can be done in a couple of seconds with my phone HTC Glacier. There's no predetermined matrix size limit. Its maximum size depends on your phone memory.

In mathematics, a matrix (plural matrices) is a rectangular array[1] of numbers, symbols, or expressions, arranged in rows and columns.[2][3] The individual items in a matrix are called its elements or entries. An example of a matrix with 2 rows and 3 columns is

\begin{bmatrix}1 & 9 & -13 \\20 & 5 & -6 \end{bmatrix}.

Matrices of the same size can be added or subtracted element by element. But the rule for matrix multiplication is that two matrices can be multiplied only when the number of columns in the first equals the number of rows in the second. A major application of matrices is to represent linear transformations, that is, generalizations of linear functions such as f(x) = 4x. For example, the rotation of vectors in three dimensional space is a linear transformation. If R is a rotation matrix and v is a column vector (a matrix with only one column) describing the position of a point in space, the product Rv is a column vector describing the position of that point after a rotation. The product of two matrices is a matrix that represents the composition of two linear transformations. Another application of matrices is in the solution of a system of linear equations. If the matrix is square, it is possible to deduce some of its properties by computing its determinant. For example, a square matrix has an inverse if and only if its determinant is not zero. Eigenvalues and eigenvectors provide insight into the geometry of linear transformations.

Applications of matrices are found in most scientific fields. In every branch of physics, including classical mechanics, optics, electromagnetism, quantum mechanics, and quantum electrodynamics, they are used to study physical phenomena, such as the motion of rigid bodies. In computer graphics, they are used to project a 3-dimensional image onto a 2-dimensional screen. In probability theory and statistics, stochastic matrices are used to describe sets of probabilities; for instance, they are used within the PageRank algorithm that ranks the pages in a Google search.[4] Matrix calculus generalizes classical analytical notions such as derivatives and exponentials to higher dimensions.

Listen Read Device Only Added Installed A Boldogan Bólogatsz egy intelligens koncert ajánló alkalmazás, több mint 3000 előadóval és 800 helyszínnel!

Ez egy béta verzió, még nagyon gyerekcipőben jár, de folyamatosan fejlesztjük egy egyre több koncert kerül bele. A hibákat kérlek emailen jelezd. Köszönjük a türelmed!

Ingyenes:

A program teljesen ingyenes és reklámok nélküli, mindenki számára.

Testreszabható:

A program az első indításkor megkérdezi: milyen zenekarokat szeretsz és hol hallgatni? Ezután már a rád szabott koncerteket ajánlja, mindezt napról-napra hatékonyabban. Persze az összes koncert is megjeleníthető egy helyen.

Kompatibilitás:

A program az android 2.2-as verziószámától, a legújabb 4.1.2-es rendszerig rengeteg kijelzőméretet és készüléket támogat, és ezek száma hétről-hétre nő! Ha a te készüléked még nem támogatott írj nekünk és gondoskodni fogunk róla!

Nincs regisztráció:

A program úgy ad testre szabott koncert ajánlatokat, hogy semmiféle regisztráció nem szükséges a használatához. Így nem kell aggódnod a személyes adataid védelme miatt.

Nem szeretsz egyedül koncertre járni?

Az koncertre klikkelve lehetőséged nyílik emailben, SMS-ben, és a telefonodra telepített közösségi alkalmazások segítségével bólogatásra hívni a többieket.

A Boldogan Bólogatsz odavezet!

A program nem csak kiírja, hogy hol ki-mikor-hol ad koncertet, de ezt térképen meg is jeleníti, amire “tappolva” -ha Google Maps telepítve van a kütyüdre- akkor oda is navigál.

Nincs mobilneted? Nem baj!

Ha nincs mobilneted, az sem baj! Szinkronizálj nappal, otthon, az irodában vagy kedvenc kávézódban egy wifi hálózaton, és este működni fog az alkalmazás offline módban is!

Bólogatsz?
