Nested For Loop Puzzle

please can anyone help me solve this Mats lab assignment

Q.Nested for loop that can solve this puzzle

thank you

Dear Samuel, you forgot to mention what kind of result you are looking for. Do you want the characters to be sorted alphabetically?

And as for all other homework questions: Please post what you have tried so far and explain, which problems you have. Of course a forum is not a place where homework questions are solved such that you can submit a solution by cut&paste.

Q.Nested for loop that can find this puzzle

T H I S

W A T S

O A H G

Jan we are New students and we really dont know much about Matlab .was given us by a lecturer on first lecture day.please help me out.thanks

[Thomas]

since this is an assignment we can only help you on the basis of what you have don so far.. and where you are getting stuck..

[Jan]

The program is called "Matlab".

The question is not clear. There is no obvious way to "find this puzzle". And this does not concern the Matlab implementation, but it is simply not defined, what you should do with these 16 characters.

THIS WHAT I FIGURED OUT BUT GET AN ERROR CAN U PLEASE CHECK THE CODES FOR ME

m=[T,H,I,S;W,A,T,S;O,A,H,G;G,G,D,T]

l=size(m)

for i=1:l(1)

for j=1:l(2)

m(i,j) = m(i,j) * 2;

end

end

JUST AS THIS WORKS OUT AND DISPLAYS,HOW DO I MAKE IT DISPLAY IN ALPHABETS.....PLEASE TRY THIS CODE FOR ME....

m=[1,2,3,4;5,6,7,8;9,10,11,12]

l=size(m)

for i=1:l(1)

for j=1:l(2)

m(i,j) = m(i,j) * 2;

end

end

Answer 1

[Sean de Wolski]

Golf:

reshape(['THISWATSOAHGGGDT'],4,4)'

Okay with for-loops:

for ii = 1
  for jj = 1
     m = reshape(['THISWATSOAHGGGDT'],4,4)';
  end
end

[Thomas]

Sean, they have to use nested for loops.. I guess thats an assignment requirement..

[Sean de Wolski]

See the edit. Now with nested FOR-loops!

[Thomas]

:) Now why did I not think about it.. I do not know how I would grade a student if they returned an answer like yours above..

Technically they used nested for loops.. :)

Answer 2

[Thomas]

You are on the right track, to get alphabets..

try

%this is your input
a=['T' 'H' 'I' 'S' 'W' 'A' 'T' 'S' 'O' 'A' 'H' 'G' 'G' 'G' 'D' 'T']

% You need the two for loops.. that you have created above.. however you have to make sure you get the length of the loops rights..

P.S. Make sure you are not inputting your matrix in the output form itself.. the input should be an array as mentioned above.. and in your question.. You have to get it into 4x4 matrix using loops..

[Samuel Awuah Botwe]

i tried this

a=['T' 'H' 'I' 'S' 'W' 'A' 'T' 'S' 'O' 'A' 'H' 'G' 'G' 'G' 'D' 'T']

l=size(m)

for i=[T,H,I,S;W,A,T,S;O,A,H,G;G,G,D,T]

for j=1:l(2)

m(i,j) = m(i,j) * 2;

end

end

but still gets errors,what am i getting wrong in the for loop

[Thomas]

You need a new matrix of size 4x4

so your for loops must go from 1:4..

You are on the right track.. however l cannot be size(m) since your input is a, l can be size(a)

[Samuel Awuah Botwe]

I TRIED THIS AND THIS WAS THE ANSWER:

a=['T' 'H' 'I' 'S' 'W' 'A' 'T' 'S' 'O' 'A' 'H' 'G' 'G' 'G' 'D' 'T']

l=size(a)

for i=1:4(1)

for j=a:A(2)

m(i,j) = m(i,j) * 2;

end

end

a =

THISWATSOAHGGGDT

l =

1 16

ans =

1

HAVE ALSO TRIED THIS AND IT GIVES ME AN ERROR (Undefined function or variable 'T'.);

a=[T,H,I,S;W,A,T,S;O,A,H,G;G,G,D,T]

l=size(a)

for i=1:4(4)

end

end

I THINK YOUR ANSWER IS GETTING ME CLOSE BUT AM NOT GETTING SOMETHING RIGHT

[Thomas]

let me break it down for you

a=['T' 'H' 'I' 'S' 'W' 'A' 'T' 'S' 'O' 'A' 'H' 'G' 'G' 'G' 'D' 'T']

for i=1:4

m(i)=a(i);

end

m

This will give you the first line.. how do you go to the next line?

nested for loop.. get the next 4 alphabets.. how? increment the value in the loop get all the alphabets....

try a google search for 'matrix reshape nested for loop', you might get some basics..

This is a homework so I cannot give help with the code directly without causing you to cheat!!

tHANKS ALOT,SO MUCH HELPFUL.GOD BLESS

[Samuel Awuah Botwe]

ITS ACTUALLY HELPFULL BUT MY ANSWERS NEEDS TO BE DISPLAYED AS ;

T H I S

W A T S

O A H G

G G D T

[Thomas]

yeah you need to input the next for loop as well.. how far is your code right now..

[Thomas]

let me give you some pseudo code... to define the logic

input array; (1x16)

start first row (i) (for loop)

place first element of input array into first row (i) of new matrix (for loop j)

increment your row (i) place the next four alphabets

and do so till you get all your elements in the new matrix..

Answer 3

[Samuel Awuah Botwe]

AM STILL FIGURING OUT WHAT AM MISSING IN THE CODE WITH THE GREAT HELP GIVEN ME.SEAN's SOLUTION WORKED RIGHT BUT I GUESS IT HASNT GOT THE FOR LOOP..........AM SOO THANKFULL FOR ALL YOUR EFFORT......I CANT WAIT TO GET IT RIGHT BEFORE I LEAVE FOR LECTURES IN 20 MIN TIME SINCE I NEED TO PRESENT IT TODAY
