\n", + "

Symmetric matrices are important because they appear in the real world \n", + " all the time. One such place is in numerically solving a model for diffusion.\n", + "

\n", + "

\n", + " The following partial differential equation models diffusion, and \n", + " is known as the heat equation.

\n", + "$$\\frac{\\partial}{\\partial t} c(x,t)=\\frac{\\partial^2}\n", + " {\\partial x^2}c(x,t) $$

\n", + "

This equation models any sort of diffusion: the diffusion of dye into a \n", + " liquid, or the diffusion of heat through a solid. Note that we have omitted constants\n", + " required to guarantee the balance of units for simplicity here.

\n", + "

\n", + "

To use linear algebra to solve this equation, we need to change this \n", + " differential equation into a difference equation.\n", + " The partial derivative with respect to $t$\n", + " can be approximated as a difference equation as follows:

\n", + "

$$\\frac{\\partial}{\\partial t} c(x,t) \n", + " \\approx \\frac{c(x,t+\\Delta t) - c(x,t)}{\\Delta t}$$

\n", + "

The second derivative can be approximated as the following difference equation:

\n", + "

$$\\frac{\\partial^2}{\\partial x^2}c(x,t) \n", + " \\approx \\cfrac{\\cfrac{c(x+\\Delta x,t) - c(x,t)}{\\Delta x}- \n", + " \\cfrac{c(x,t) - c(x-\\Delta x,t)}{\\Delta x}}{\\Delta x} = \\cfrac{c(x+\\Delta x,t) \n", + " - 2c(x,t)+ c(x-\\Delta x,t)}{(\\Delta x)^2}$$

\n", + "

We can rearrange this difference equation to find an expression \n", + " at the grid point x at the time step $t + \\Delta t$ as \n", + " follows:

\n", + "

$$c(x,t+\\Delta t) = c(x,t) + \\frac{\\Delta t}{(\\Delta x)^2}\n", + " (c(x+\\Delta x,t)-2c(x,t)+c(x-\\Delta x,t))$$

\n", + "

Notice that every term on the right hand side only depends \n", + " on the values at time step t. So we can rewrite this as a matrix \n", + " equation, in terms of a vector c(t) whose entries are points \n", + " $x$ separated\n", + " by $\\Delta x$

\n", + "

$$ c(x,t + \\Delta t) \\approx c(x,t) + \\Delta t \\frac{\\partial}{\\partial t}c(x,t) = c(x,t) + \\Delta t \\frac{\\partial^2}{\\partial x^2}c(x,t).$$

\n", + "

$$ c(t + \\Delta t) = (I - \\frac{\\Delta t}{(\\Delta x)^2}A)*c(t)$$

\n", + "

In this problem, we provide you with the code to observe the evolution of this \n", + " differential equation, which describes diffusion. We start by discretizing the \n", + " variable x, which we represent as a vector of 101 points lying on the \n", + " interval from 0 to 1. Thus our meshwidth in space,$\\Delta x$,\n", + " is 0.01. We start with an c(x,0) = c is the initial concentration, \n", + " which we take to be a Gaussian distribution, or a bell curve.

\n", + "

\n", + "

\n", + " Your job is to create a negative second difference matrix A. And, to plot the \n", + " concentration vector C(:,t) for (at least) 3 later times. (See further \n", + " instructions within the code body.)\n", + " \n", + " \n", + "

A note about A:\n", + " The dimension of A is 101x101. \n", + " The matrix A must enforce boundary conditions!!!! Here, this means we will \n", + " make the first row and column zero, and the last row and column zero. You can see\n", + " what happens in the plot if you don't enforce this condition!\n", + " Note that the diagonal of A will be 2, the super and sub diagonals will be -1, \n", + " except at the boundary, where all entries will be zero.\n", + "
