The equation for a linear function is: y = mx + b, Where: m = the slope , x = the input variable (the “x” always has an exponent of 1, so these functions are always first degree polynomial.). b = where the line intersects the y-axis. The equation, written in this way, ...
We learn in calculus that a maximum occurs at a zero of the derivative. But this function is not differentiable in the vicinity ofπ2. We can analytically differentiatef(x)using the Symbolic Math Toolbox. diff(F) ans =cos(x) (tan(sin(x))2+1)−cos(tan(x)) (tan(x)2+1) ...
The input data set x in this chart was generated by choosing values of Xn, for n = 1,...,N, spaced uniformly in range [0,1], and the target data set t was obtained by first computing the corresponding values of the function sin(2πx) and then adding a small level of random noi...
returns the values atxxof the cubic spline interpolant to the given data (x,y), using the not-a-knot end condition. This interpolant is a piecewise cubic function, with break sequencex, whose cubic pieces join together to form a function with two continuous derivatives. The "not-a-knot" ...
The threshold must be far enough out in the tail of the original distribution for the approximation to be reasonable. The original distribution determines the shape parameter, k, of the resulting GP distribution. Distributions whose tails fall off as a polynomial, such as Student's t, lead to...
Line 27 of the example shows how we call the NavierStokes function to tell Modulus Sym that we want to solve the Navier-Stokes equations. We set the kinematic viscosity nu=0.01 and the density rho=1.0. We set time=False because this is a steady-state problem (time is not a variable),...
SOLUTIONSince f is a polynomial, our first attempt should be to em-ploy Theorem 3 and substitute 0 for h. However, we see that this gives us“0/0."Knowing that we have a rational function hints that some algebra will help. Con-sider the following steps:This matches our previous approxim...

functionAssociatedLaguerrepolynomialGegenbauerpolynomialRecursionUsing the theory of orthogonal polynomials, their associated recursion relations and differential formulas we develop a new method for evaluating integrals that include orthogonal polynomials. The method is illustrated by obtaining the following integral...
To track the signal a little more closely, you can use a weighted moving average filter that attempts to fit a polynomial of a specified order over a specified number of samples in a least-squares sense. As a convenience, you can use the function sgolayfilt to implement a Savitzky-Golay sm...
