MATLAB: Lagrange Multipliers

lagrange multipliers

Use the Lagrange mulipliers to find the points on the parabola y=x^2+2x which are the closest to the point(-1,0).

here is a nudge to solving your problem

syms x y L
d = ???                   % for you to fill out; distance from (-1,0)
g = d+L*(x^2+2*x-y)       % constraint for given parabola
% additional operations here

show some effort, and some additional help may be forthcoming

pointx and pointy are two vectors of data values, x is a vector of points where you want to interpolate. For example:

x = 0:10;
y = x.^2;
xx = linspace(0,10);
yy = lagrange(xx,x,y);
plot(x,y,'o',xx,yy,'.')

As an aside, with no offense intended to Calzino, there are other options available for interpolation. Firstly, of course, interp1 is a standard MATLAB function, with options for linear, cubic spline, and PCHIP interpolation. Cleve Moler (aka The Guy Who Wrote MATLAB) also has a Lagrange interpolation function available for download.

MATLAB: How can i plot a mathematical expression of x and y

You need to use fimplicit() to directly draw such a function.

fimplicit(@(x,y) (1+x).^2 + (2-y).^2 - 4)
