Pensando nas necessidades de estudantes de engenharia, entusiastas de matemática e afins, pode-se considerar que realizar operações com matrizes é uma das atividades mais trabalhosas e repetitivas pertencentes ao campo da matemática geral. Com o intuito de facilitar processos que envolvem a aplicação de tais conceitos, foi criada a melhor calculadora de matrizes da App Store: o CalcMatrizes! Se há algo chato em mexer em matrizes e suas operações, é realizar longos processos de escalonamento, como quando realizamos inversões, ou resolvemos equações matriciais com proporções que nos fazem perguntar-nos se o resultado que obtivemos é realmente o correto. Com isso, eis as funcionalidades que o CalcMatrizes oferece para que seus problemas sejam resolvidos: - Inverter matrizes - Transpor matrizes - Multiplicar matrizes - Adicionar/subtrair matrizes - Multiplicar matrizes por escalares - Realizar escalonamento (reduzido e não reduzido) - Resolver equações matriciais, do tipo: - AxX=B - BxX=A - XxA=B - XxB=A (em que A e B são, respectivamente, a primeira e segunda matrizes escritas no processo de resolução) Acima de tudo, além de aceitar números como as entradas da matriz, o CalcMatrizes também aceita o preenchimento de campos utilizando letras (que vão de a-i), de modo a permitir que cálculos sejam realizados em função de variáveis, e não apenas números conhecidos. Com uma ferramenta dessas em mãos, não há porque se frustrar com problemas tão chatos e desgastantes quanto trabalhar com uma matriz 4x4 simplesmente com uma caneta e uma folha de papel!

Verdict

The call

The clearest difference is rating: Electrical Calculations at 4.6 against CalcMatrizes's 3.0. Electrical Calculations also leads on update cadence (every 2 weeks vs every 5 months) and ratings volume (129 vs 2). CalcMatrizes's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.
