WebUse la función diff para aproximar derivadas parciales con la sintaxis Y = diff (f)/h, donde f es un vector de valores de función evaluado en algún dominio, X, y h es un tamaño de paso apropiado. Por ejemplo, la primera derivada de sin (x) con respecto a x es cos (x) y la segunda derivada con respecto a x es -sin (x). An attracting fixed point of a function f is a fixed point xfix of f such that for any value of x in the domain that is close enough to xfix, the fixed-point iteration sequence The natural cosine function ("natural" means in radians, not degrees or other units) has exactly one fixed point, and that fixed point is attracting. In this case… foam is a very effective smothering agent and
