counting the values and variables

I have a  dataset 50x62

for example

S=['F' 'D' 'C' 'D' 'C';'C' 'C' 'F' 'D' 'F']

these variables are my output from one operation,now i want to count the number of variables

here i have 2 rows and number of variable is 3

so i need as

F D C
1 2 2
2 1 2

PLEASE HELP

[kash]

wayne length gives value as 3,but i need as above

What about a nice loop:

S=['F' 'D' 'C' 'D' 'C';'C' 'C' 'F' 'D' 'F'];
x = sort(unique(S));

fprintf('%c\t', x')
fprintf('\n')
for ii = 1:size(S, 1)
  for jj = 1:length(x)
    temp(jj) = length(find(S(ii, :) == x(jj)));
  end
  fprintf('%d\t', temp);
  fprintf('\n')
end

DAniel i get error Function is not defined for 'cell' inputs.

and plz tell in which variable these output are stored,i need it because for next operartion

[Daniel Shub]

If your S is a cell array and not a char array, then of course your are going to get an error. If S cannot be easily converted to a char array, then you are going to need a very different answer.

As for which variable the output is saved as, the output is not saved it is simply displayed. You didn't ask for saved output. Think about the loops and what temp is doing. How would you modify "temp" to save all the data... Try and figure it out yourself, and when you get stuck ask a new question.

Daniel S is an cel array ,can u please tell hoe to perform and save the output in variable,because i dont know hoew to process plz

[Daniel Shub]

No. If you are not willing to work at it, then I am not willing to help you.

Daniel i used char and then reshaped it but get some extra values

C D

0 62 1.168713e+001 8.909025e+000 1.202819e+001 9.658573e+000 9.563827e+000

[Daniel Shub]

You probably want to clear temp before the loop ...

[kash]

ok daniel for displaying values in output

i did

[temp]=temp(jj),after temp(jj) = length(find(S(ii, :) == x(jj)));

i did not get the result,temp displays each value of row,so i tried to cancatanate it

[kash]

for ii = 1:size(S, 1)

for jj = 1:length(x)

temp = length(find(S(ii, :) == x(jj)));temp(jj)=temp;

end

i tried this also but not getting exact answer

[Daniel Shub]

What does the ii loop do? What does the jj loop do? Are you saving the ii loop anywhere? What about temp(ii, jj)?

[kash]

temp(ii) is 1,temp(jj)is 2

ii loop calculates the row of origal value(S),and jj calculates the column unique variables

[kash]

i tried not getting for final time an u code for me for saving output in a variable

   S = ['F' 'D' 'C' 'D' 'C';'C' 'C' 'F' 'D' 'F'];
   NumVars = length(unique(S));

thanks wayne another

if i have

A=[1 2 3 2 1 ;2 3 1 1 1];

here i want to count the number of 1's,2s,3's for each row so i get

and store i different variables

A B C

2 2 1

3 1 1
