MATLAB: Plot separate histograms.

histogramMATLAB

Hi, I want to plot two separate histograms for the following data. A histogram having values more than zero from the column in the far right corner and another one when the value is zero. Any help is much appreciated. Thank you.

Assuming this is a n x 5 matrix, the following commands will give you separate matrices based on your condition.
% x being your initial matrix
matrix_non_zero = x(x(:, 5) > 0, :);
matrix_zero = x(x(:, 5) == 0, :);
Now you can plot an histogram for these matrices based on your requirements.
