like i have the following code for the above:

function count clc; a=[1 2 3 3 4 5 5 5 5 5 6 6 6 6]; u=unique(a); for n=1:length(u) answer(n,:)=[u(n) length(find(a==u(n)))]; end disp(answer); end

output is:

1 1 2 1 3 2 4 1 5 5 6 4 i want to find the maximum value from the list (1 1 2 1 5 4) i.e from the 2nd column of the output...

2nd column of output displays the number of times the given element occurs.

can anyone tell me how to solve it?

Accepted answer

[maxcount, maxidx] = max(answer(:,2)); answer(maxidx,1), 'occurred', maxcount

That's just the histogram:

% Create sample data. a=[1 2 3 3 4 5 5 5 5 5 6 6 6 6 9 9 11 11 18] % Get the histogram with bins every 1 wide from 1 to the max value of a. numberOfBins = max(a)-min(a)+1 % Assumes integer a values. counts = hist(a, numberOfBins) % Find out where the histogram is maximum. [maxValue, maxIndex] = max(counts) % Print out information to the command line. fprintf('The most frequently occurring number is %d, which occurs %d times.\n',... maxIndex, maxValue);

In the command window:

a = 1 2 3 3 4 5 5 5 5 5 6 6 6 6 9 9 11 11 18 numberOfBins = 18 counts = 1 1 2 1 5 4 0 0 2 0 2 0 0 0 0 0 0 1 maxValue = 5 maxIndex = 5 The most frequently occurring number is 5, which occurs 5 times.

You probably redefined hist to be a variable in your program, thus blowing away the built-in function. What do these say:

whos hist which -all hist
