Tema 2<\/strong> (15 puntos). Dos matrices A<\/strong> y B<\/strong> se pueden multiplicar si el n\u00famero de columnas de A<\/strong> coincide con el n\u00famero de filas de B<\/strong>.<\/p>\n\n\n\n

A<\/strong>m x n<\/sub> x B<\/strong>n x p<\/sub> = C<\/strong>m x p<\/sub><\/p>\n\n\n\n

El elemento C<\/strong>ij<\/sub> de la matriz producto se obtiene multiplicando cada elemento de la fila i<\/strong> de la matriz A<\/strong> por cada elemento de la columna j<\/strong> de la matriz B<\/strong> y sum\u00e1ndolos.<\/p>\n\n\n\n

Realice una funci\u00f3n producto<\/strong>(A<\/strong>,B<\/strong>) que permita realizar el producto entre una matriz A<\/strong> de tama\u00f1o de m<\/strong>xn<\/strong> y un vector B<\/strong> de tama\u00f1o n<\/strong>.<\/p>\n\n\n\n
