MATLAB: Write a function drawBox which draws boxes on the screen

homeworkMATLABmatlab function

I got a task but I am confused. This is My task The function is called with a character (ch) as the first argument and two positive integers which represent the width and the height of the box to be drawn. It automatically draws a box with the character (ch) by the specified width and height. Can Anyone help me out with the task.

function drawBox(str,w,h)
ch = [0. 0.] ;
%%get four corners of box
N = 20 ;
x = linspace(ch(1),ch(1)+w,N) ;
y = linspace(ch(2),ch(2)+h,N) ;
[X,Y] = meshgrid(x,y) ;
X(2:end-1,2:end-1) = NaN ;
Y(2:end-1,2:end-1) = NaN ;
x = X(~isnan(X)) ;y = Y(~isnan(Y)) ;
plot(x,y,'.w') ; hold on
text(x,y,str)
axis off

MATLAB: Draw empty box by use for loop

function []=drawBox(s,w,h)% s is char 
for i= 1:w
   for j=1:h
     if i==1||i==w||j=1||j==h
        fprintf('%s \n',s) ;
      else
        fprintf('');
     end
   end
   end

MATLAB: Going from switch case construct to loop

put your current code in a function such as

function outputMorse=char2morse(inputeChar)

So this function gets a character and returns the morse code. Put your code that you have there. Name that file char2morse.m (or whatever you gonna name that function.

Then write another code

function outputMorse=string2morse(inputString)
validateattributes(inputString,{'char'},{'vector'})
for i=1:numel(inputString)
  outputMorse{i}=char2morse(inputString(i));
end

put this in a file called string2morse.m (or again whatever you want to name this function.)

Now you can call this function in other codes like:

morseCode=string2morse('SOS')

NOTE: Based on your code and output type you need to change the above code. But the general structure would be like that.
