I calculate an image histogam using this code:

a=imread('mypic.jpg');
b=rgb2gray(a);
[count,x] = imhist(b);

Now, I'd like to export the values of 'count' and 'x' to 2 separate columns in an Excel speadsheet. Please help!

Thank in advance!

T = table(x, count, 'VariableNames', {'Pixel Value', 'count'});
writetable(T, 'NameOfTheSpreadsheetGoesHere.xlsx');
