定义决策域\mathcal { R } _ { k }表示在这个区域中的x属于\mathcal { C }_k类。 \begin{aligned} p ( \text { mistake } ) & = p \left( \mathbf { x } \in \mathcal { R } _ { 1 } , \mathcal { C } _ { 2 } \right) + p \left( \mathbf { x
A famous unsolved problem in the theory of polynomial interpolation is that of explicitly determining a set of nodes which is optimal in the sense that it loads to minimal Lebesgue constants. A solution to this problem is presented for the first nontrivial case of cubic interpolation. This ...
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, is called the slope-intercept form. These functions can also be written as y = ax ...
Here, consider only real values of x by setting the assumption that x is real. Get assume(x,"real") As an example, create a rational expression (such as a fraction where the numerator and denominator are polynomial expressions). Get f = (3*x^3 + 17*x^2 + 6*x + 1)/(2*x^...

This demonstration shows how to find extrema of functions using analytical and numerical techniques using the Symbolic Math Toolbox™.
This example shows how to solve polynomial equations and systems of equations, and work with the results using Symbolic Math Toolbox™. Gaussian quadrature rules approximate an integral by sums ∫baf(t)w(t)dt≈n∑i=1f(xi)αi. Here, the xi and αi are parameters of the method, ...
