Element-wise operations | 599c333915e0ea32d04d4bec | 5 | Operações elementares |
Description
Implemente operações básicas de matriz matricial e matricial escalar.
Implemento:
::* Adição
:: * subtração
:: multiplicação
:: * divisão
:: * exponenciação
O primeiro parâmetro será a operação a ser executada, por exemplo: "m_add" para adição de matriz e "s_add" para adição escalar. O segundo e terceiro parâmetros serão as matrizes nas quais as operações serão realizadas.
