how do these function (separate functions)

clc; clear;

input=['MATLAB'];

for i= 1:length(input)

fprintf(input(1:i))

fprintf('\n')

end

%-----------------------------------------------------------------------------------------

clc; clear;

for j=length(input):-1:2

fprintf(input(1:j-1))

fprintf('\n')

end

for x= 5:-1:1

msg=[];

for y = 1 : x

number= x*y;

msg = [msg number];

end

disp(msg);

end

%-----------------------------------------------------------------------------------------

clc; clear;

height = 10;

for i= 1:height;

for j= i:height;

if mod(i,2)==0

fprintf 'O'

else

fprintf 'X'

end

end

fprintf '\n'

end

Hi @Jacob,

I understand that you are trying to define all the functions in one file using local functions in MATLAB. Here is how you can organize all three functions into a single script file. Note that only the main function or script code can directly call these local functions; they are not accessible from outside this file.

% Main script section (if needed)
clc; clear;
inputStr = 'MATLAB';
printChars(inputStr);
displayMultiplications();
printPattern(10);

% Local functions below

function printChars(input)
    for i= 1:length(input)
        fprintf(input(1:i))
        fprintf('\n')
    end
    
    for j=length(input):-1:2
        fprintf(input(1:j-1))
        fprintf('\n')
    end
end

function displayMultiplications()
    for x= 5:-1:1
        msg=[];
        for y = 1 : x
            number= x*y;
            msg = [msg number];
        end
        disp(msg);
    end
end

function printPattern(height)
    for i= 1:height
        for j= i:height
            if mod(i,2)==0
                fprintf('O')
            else
                fprintf('X')
            end
        end
        fprintf('\n')
    end
end

I hope this helps!
