I am new to MATLAB.
I need to test correlation function on a data set in the form of a table(1x9757). When i input this into the correlation function, a new matrix if formes with size 9757x9757. But all the values in it are 'NaN' and in the workspace (where the size and minimum and maximum values of variables is mentioned), in the column of minimum and maximum value a message comes that says, 'Too many elements'.
Could anyone please help me with this. I am stuck on this from a very long time.
Thanks!

Strange. If your matrix is 1 * 9757 , then there is no correlation to be calculated and the result of corr() should be one. Some data would help to understand the problem.
Cheers!

Hi Abhivyakti,
I know the question is past old however for any one wondering Jose is right. It should come to one
data = rand(1, 9757);
dataTable = array2table(data);
disp(dataTable(:, 1:5));
data1 data2 data3 data4 data5 _______ _______ _______ _______ _______ 0.10003 0.88021 0.78291 0.13145 0.85536
correlationMatrix = corr(dataTable{1, :}', dataTable{1, :}');
disp('Correlation coefficient:');
Correlation coefficient:
disp(correlationMatrix);
1
