Description. XI is a p -by- n matrix, representing p points in n -D space. . 0003 % 0004 % GRIDDATA is not recommended. XI can be nonuniform. Start by generating n = 5000 points at random in three-dimensional space, and computing the value of a function on those points. Geralmente, os erros HTML são causados por ficheiros ausentes ou corruptos. yi = griddatan(x,y,xi) fits a hyper-surface of the form y = f(x) to the data in the (usually) nonuniformly-spaced vectors (x, y). This is true for most cases. The surface always passes through the data points defined by x and v. MATLAB Function Reference : Functions - Alphabetical List. This is true for most cases. values ndarray of float or complex, shape (n,). For more information, see Array vs. The surface always passes through the data points defined by x and v.
