# Description

This is a simple, OPEN SOURCE and FREE matrix calculator. Support some simple operations with matrices (example:AxB, Inverse, Determinant, Eigenvalues).

Now, it's working only with the real numbers, but in the future we will add the complex numbers.

Please be patient, this is an RC version, and please report the bugs in emails!

Please donate us,

Thanks!

Does what its sposed to! Basic enough for beginner with a little explanation of processes which is good too! a few other maths apps look great but impossible to find how to input a simple number and navigate, this one doesn't try to be too fancy.

Mike Fontanazza

Disappointed Only uses the number pad on galaxy s3.. won't allow any other characters to separate numbers. Was usable with my incredible but since upgrading phones its rough to use..

Rodrigo Giorgi

It would be a 5 star app Is impossible to type matrix with rows longer than 22 characters.

User reviews

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.

Awful This one is awful, but you guys should try a new app called Matrix Mate, the answers are actually right and the interface is ALOT better!

Absolutely terrible Doesnt do anything right I ask for inverse it gives me the welcome page Epic fail,terrabad,anything is better then this piece

After calculating something, clicking on why, hitting the back button, and trying a new calculation, the answer doesn't update for new calculation.

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 4.4.2-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!
