REALIZAR EJERCICIOS ADICIONALES


Elaborar una aplicación con las siguientes opciones

1. Generar.- se tiene una matriz de n filas por m columnas que representa las alturas en un espacio 3d al principio todos las altura son cero , se generar un nro aleatorio de filas y columnas entonces la celda A(rx,ry) crece en 1 y asi sucesivamente hasta llegar a altura máxima de 15 , si la altura es mayor que 15 el elemento A(ry,yx) se vuelve a cero

2. Mostrar. Mostrar la matriz generada usando colores de acuerdo a las alturas3. Recuperar. Recuperar un archivo grabado de Excel 4. Grabar .- graba el contenido de la matriz en un archivo de texto con

delimitadores para Excel5. Simular. Simula las variaciones de las celdas de la matriz 3D un numero

determinado de veces6. Función. Genera los valores de una función y lo carga a la matriz7. Sumar.- un ser camina aleatoriamente por la matriz y va haciendo crecer de 1

en 1 las alturas 8. Restar. un ser camina aleatoriamente por la matriz y va haciendo decrecer de

1 en 1 las alturas9. Salir
