I found on page 145 that Natural cubic splines are linear be. dot_l2, a MATLAB library which estimates the L2 dot product of two functions over an interval [A,B], with the functions entered as a string. What you have provided would be a good answer on a LaTeX forum, but it doesn't explain how to use this information in Matlab. If you haven't done so already, you first need to install the MATLAB interface. There are endless solutions for inequalities.

Given a set of (n+1) data points and a function f, the aim is to determine a polynomial of degree n which interpolates f at the points in question. Em probabilidade e estatística, a distribuição triangular é a distribuição de probabilidade contínua que possui um valor mínimo a, um valor máximo b e uma moda c, de modo que a função densidade de probabilidade é zero para os extremos (a e b), e afim entre cada extremo e a moda, de forma que o gráfico dela é um triângulo.
