PLEASE CODE IN MATLAB: Structuring the Script File

Since we have not yet covered loops or branching, you will enable repetition of the move operation by dividing the script into $3$ sections: initialization, movement, and reporting.

You can either create a new MATLAB script $(.$m$)$ file or use the livescript template provided on Carmen. Ensure you save it with a name that indicates the assignment and your name $($for example, Application$3\_$Smith.m$).$ To divide the script into sections, use a double$-$percent sign $(\%\%).$ If you are creating your own script file, please see the template as a reference.

Initialization Section

The first section should do the following:

Clear the workspace and command window and close any figure windows

Create a $10$x$10$ grid matrix of all zeros $($this is the matrix that your robot will occupy$)$

Initialize the robot$$s coordinates to be near the center $[$can be $(5,5)$ or $(6,6)]$ of the grid matrix by

setting that element of the grid matrix to $1$

Create a second $10$x$10$ matrix to represent the targets; initialize to all zeros as well

Using the input$()$ function, prompt the user for the number of targets $($should be between $1$

and $100).$

Randomly choose that number of elements of the target matrix and set them to $1.$ This line will accomplish that $($assuming that your target matrix is called target and that the number of targets entered by the user is num$\_$targets $$ you may use whatever variable names you like$)$:

targets$($randi$(100,[$num$\_$targets,$1]))=1$;

NOTE:this will not necessarily give unique target positions,so there is a chance that the number of targets placed in the matrix will be less than the number entered by the user $($this is okay$)$

Display the robot$$s location using the provided show$\_$image function.

Set the title of the figure window so that it indicates the robot$$s position. $($You can do this using

string concatenation with the $+$ operator$)$

$3.$ Movement Section

The second section should do the following:

Prompt the user for how far to move the robot in the columns and rows

o NOTE:Remembertherobotisactuallylocatedinamatrix,sotheposition$(1,1)$is located

near the TOP left when graphed, not the BOTTOM left $($what we typically imagine as the origin$).$ What we typically think of as movement in the x direction is actually movement between columns and movement in the y direction is actually movement between rows

Update the robot$$s position

Update the grid matrix $$ set the element for the previous position to $0,$ and the new position to $1$

Display the robot$$s position just as in the initialization section $($including title with correct robot

position location$)$

Determine if there is a target at the robot$$s new coordinates. To accomplish this, perform an element$-$wise multiplication of the grid matrix by the target matrix, and take the sum of all elements. The result will be $0$ if there is not a target at the robot$$s location, or $1$ if there is$.$

Set the element of the target matrix corresponding to the robot$$s position equal to $0.($That is$,$

once a target is found, remove it from the target matrix.$)$

Print to the command line $($using either disp or fprintf$)$ a message $[$indicating whether a

target was found. Since we have not yet covered if statements, the easy way to do this is to select one of two messages from an array using indexing. $($See the example message array in the script template above.$)$

Update the number of moves and number of targets found $$ the former always increases by $1,$ while the latter increases by $1$ only if a target is found.

$4.$ Reporting Section

The third section should do the following:

Print to the command window a message indicating how many targets were found and how many moves were made

Print to the command window how many targets remain $$ you can determine this by summing the entire target matrix

Display the targets using show$\_$image.
