Variance of a histogram in matlab - Signal Processing Stack Exchange histogram (q,1000); %q is the aforementioned vector of values. Now, I have to calculate the variance of each of the 2 gaussian distributions that appear in the image. I know that the function var (x) gives you the variance of a vector, so I tried with: h = hist (q,1000); h1 = h (1:500); h2 = h (500:1000); v1 = var (h1); v2 = var (h2); But it's ...

How to plot a Histogram in MATLAB - GeeksforGeeks Basically, the histogram contains several bins. Bins are non-overlapping intervals in which the data is spread. In MATLAB we have a function named hist () which allows us to plot a bar graph. Syntax: hist (X) where X represents the data. The X is a vector. The histogram function uses an algorithm that returns bins and bins width are equal. matlab - Facing problem in plotting histogram of DCT coefficient of an ... What could be more successful would be to compare the DCT coefficient histograms (DC coefficient removed) on each of the $8\times 8$ blocks, raw and compressed, and then combining the coefficients of all the blocks.
