Matrix Dimensions Must Agree

i got error in my code,,

it says Error using ==> / . Matrix Dimensions Must Agree

this is my code

a= input ('The number of participant :');

for c=1:a

str1 = ['Input Your Name :'];

str2 = ['Input Your First Score :'];

str3 = ['Input Your Second Score :'];

str4 = ['Input Your Third score :'];

b{c,1} = input(str1,'s');

b{c,2} = input(str2);

b{c,3} = input(str3);

b{c,4} = input(str4);

end

disp(b)

[m,n]= size (b);

Mb=max([b{:,2}])

fooCell = num2cell(NM);

for i=1:c

    for j=1:3

        R{i,j}=Mb{:,j}/b{i,j};

    end

end

That error pointing at "/" in R{i,j}=Mb{:,j}/b{i,j};

anybody knows what's my fault?

please help me :)

Answer 1

[Azzi Abdelmalek]

R{i,j}=Mb{:,j}/b{i,j};

what is Mb{:,j}?

and why Mb=max([b{:,2}])?

[baby]

Mb is for decide the highest value in matrix "b"

anyway, is that wrong?

[Azzi Abdelmalek]

no it is not, the highest is

 bb=cellfun(@double,b(:,2:end))
 Mb=max(bb(:))

b{1,1} is a string, so you are trying to divide a matrix by a character vector.

By the way, have a look at the documentation for rdivide and compare it to the documentation for mrdivide
