Solve problem #$2$ using matlab, provide matlab code. Problem $1$ given as reference:

#$1$: A data file is provided for use in all of the following questions. Each row of the data file

contains $4$ pieces of data: $P(t_i)Q(t_i)R(t_i)t_i$ for values of i from $1$ to $N.$

Download the data file from here, and construct a vector function

at discrete times $r(t_i).$ Plot the curve in $3$ dimensions produced by these points using the Matlab

command plot $3$ as discussed in the tutorial. Set the LineWidth equal to $2.$

Problem # $2$: A second curve will be created from the same data set that you downloaded in Problem #$1$ above. For this one,

you will use

Following the directions in the tutorial, use forward difference quotients on the discrete points of this new curve to

create unit tangent vectors $T(t_i),$ and unit normal vectors $N(t_i),$ for all $i.$

Next find the unit binormal vectors, $B(t_i)$ at each point i using the cross function in Matlab. Enter the three

components of $B(t_i)$ for $i=798$ into the answer box below, separated with commas.
