$2)$ read binary data $(20$ points$)$

read the binary data generated with the matlab code stored in the file 'data.bin'

you need the following parts

$-$ open the file and assign a file handle

$-$ read the binary data and store the data $($output$)$ in binary$\_$data

$-$ close the file

$-$ unpack the data

$*$ set a variable nx $=1001$

$*$ set a variable nt $=500$

$*$ compute a variable n which is the product of nx and nt

$*$ set a variable fmt $=\text{'}$d$\text{'}*($n$*3)$

$*$ call the struct.unpack function with the inputs fmt and binary$\_$data return the output to data

$*$ reshape the data array using the following function: np$.$array$($data$).$reshape$(($nt$,$ nx$,3))$

$-$ data is now a $3$d array of the dimensions$($nt$,$nx$,$nvars$)$ where nt is the number of time instances, nx is the number of lcoations and nvars is the number of variables $($here $3$: x$,$ t and p$)$

$-$ save the data in $3$ separate $2$d arrays called x$,$t and p as follows

$*$ x $=$ data$[$:$,$ :$,0]$

$*$ t $=$ data$[$:$,$ :$,1]$

$*$ p $=$ data$[$:$,$ :$,2]$
