Replacing matrix A with another matrix that counts entries from matrix B

Sorry for the confusing title and I will explain everything below.

I would like something that does the following (better if loops are not used): A code that replaces the entire matrix A (size unknown but all entries are unique integers) by counting the number of same entries as A has from matrix B (size unknown, all integers, might have redundant entries).

Example.

Input is A = [1 3 5; 6 4 11];   B = [3 3 2 1 4 6 10 29; 4 2 1 1 99 1 7 29; 8 2 1 6 7 6 11 1]；

After using the code to replace A, the output should be A = [6 2 0; 3 2 1]; (since there are 6 of number 1, 2 of number 3, no number 5, 3 of number 6, 2 of number 4 and only one of number 11).

Thanks very much for your help. Please let me know if you have any questions.

A = [1 3 5; 6 4 11]; 
B = [3 3 2 1 4 6 10 29; 4 2 1 1 99 1 7 29; 8 2 1 6 7 6 11 1]
A=arrayfun(@(x) sum(sum(ismember(B,x))),A)

% or

A=arrayfun(@(x) sum(ismember(B(:),x)),A)

I hope this isn't your homework or you can't turn this in:

% Sample data:
A = int32([1 3 5; 6 4 11])
B = int32([3 3 2 1 4 6 10 29; 4 2 1 1 99 1 7 29; 8 2 1 6 7 6 11 1])
% Now get the histogram.
edges = unique(A(:))
counts = histc(B(:), edges)

In the command window:

A =
           1           3           5
           6           4          11
B =
           3           3           2           1           4           6          10          29
           4           2           1           1          99           1           7          29
           8           2           1           6           7           6          11           1
edges =
           1
           3
           4
           5
           6
          11
counts =
     9
     2
     2
     0
     7
     1

It's not homework. I'm writing a function for predicting winning chances for Texas Hold Them poker game for fun. I'm planning on doing a GUI for the function on post it on the forum.

Thanks very much

And, how come that number 1 from matrix B has 9 counts? There are only 6 of number 1 in matrix B I thought.

Dear predecessors, I am a beginner to matlab. Recently i am studying a thesis about my major, in which matlab is used. Something goes wrong while repeat the process of the thesis and i can't find a solution or help from my friends. Would you kindly take a few mins to have a look my question and give me some sugguestion? This is my question: http://www.mathworks.com/matlabcentral/answers/77715-how-to-find-the-polynomial-coefficients-of-two-array

Many thinks!

Sorry - forgot to eliminate the elements in B that weren't in A so the 2's got counted. Try this code:

% Sample data:
A = int32([1 3 5; 6 4 11])
B = int32([3 3 2 1 4 6 10 29; 4 2 1 1 99 1 7 29; 8 2 1 6 7 6 11 1])
% Eliminate elements of B that aren't in A.
inA = ismember(B(:), A(:))
B = B(inA);
% Now get the histogram.
edges = unique(A(:))
counts = histc(B(:), edges)

Results:

counts =
     6
     2
     2
     0
     3
     1

[ii,jj] = ismember(B,A);
out = reshape(accumarray(jj(ii),1),size(A));
