Hello, In code below i have to specify the range for columns but i have 100 set of excel files in that with different column length so how to specify in that case
[~,~,raw]=xlsread(fullFileName,'Results','B:B'); % reads all rows in Column B
raw(any(cellfun(@(x) any(isnan(x)),raw),2),:) = []; % removes all NaN entries#
data = reshape([raw{:}],size(raw));
Blob = data(:,1);
Area = data(:,2);
clearvars data raw;
h=bar(Area);
After then I would like to plot them I am getting error

To read all the rows just write
[a,b,c]=xlsread('filename.xls')
