SE PRESENTA UN MÉTODO MATRICIAL PARA EVALUAR LAS FUNCIONES ESFEROIDALES ANGULARES COMO ALTERNATIVA AL MÉTODO ORTODOXO. SE IDENTIFICAN LAS ONDAS PLANAS COMO FUNCIONES GENERADORAS DE LAS FUNCIONES ESFEROIDALES, MOSTRANDO SUS DESARROLLOS EXPLÍCITOS.AbstractA MATRIX METHOD TO EVALUATE THE ANGULAR SPHEROIDAL FUNCTIONS IS PRESENTED AS AN ALTERNATIVE TO THE ORTHODOX METHOD.PLANE WAVES ARE IDENTIFIED AS GENERATING FUNCTIONS OF THE SPHEROIDAL FUNCTIONS SHOWING THEIR EXPLICIT EXPANSIONS.A MATRIX METHOD TO EVALUATE THE ANGULAR SPHEROIDAL FUNCTIONS IS PRESENTED AS AN ALTERNATIVE TO THE ORTHODOX METHOD.PLANE WAVES ARE IDENTIFIED AS GENERATING FUNCTIONS OF THE SPHEROIDAL FUNCTIONS SHOWING THEIR EXPLICIT EXPANSIONS.
