July 8, 2013 - histwc is a simple utility to construct weighted histogram.

July 22, 2020 - I am relatively new to MatLab so I need some assistance with this task. Basically, I have two arrays that I want to weigh the other with and create an overall histogram. To explain this better, I have an array that contains the bins (A) and an array with weighted values (B):

July 11, 2013 - For example, if 11 comes up five times in the dataset but one is weighted 0.5, the frequency count in the histogram for 11 will be 4.5. ... https://www.mathworks.com/matlabcentral/answers/81805-how-to-make-a-weighted-histogram-with-specific-bins#comment_159481

March 25, 2014 - Calculates 2D weighted histogram and plots in color

July 11, 2019 - Just use accumarray to sum the weights in each bin. ... https://www.mathworks.com/matlabcentral/answers/471261-how-to-construct-a-weighed-2d-histogram#comment_723845

May 10, 2023 - Finally, we create a histogram using the histogram function and specifying the bin edges and calculated weighted counts. We set the Normalization option to 'probability' to create a probability density function.

July 30, 2016 - This is a very fast implementation of weighted histogramming whose core is the accumarray function. Brent (2026). histwv(v, w, min, max, bins) (https://www.mathworks.com/matlabcentral/fileexchange/58450-histwv-v-w-min-max-bins), MATLAB Central File Exchange.

June 18, 2022 - I am using a nx2 array to populate a Histogram 23 2 12 2 85 3 38 3 12 4 09 2 97 4 and want a histogram (or bar chart?) with second attribute as the X axis and the first...

December 5, 2014 - In reality I have really big arrays so am hoping to avoid a loop (the simple way would be to just loop over bin indices and sum/scale by intensity within the loop to calculate the weighted histogram that way but that would take too long with my really long arrays). ... https://www.mathworks.com/matlabcentral/answers/165599-is-there-any-way-to-scale-histogram-elements-so-instead-of-simple-count-get-weighted-sum-within-bins#comment_374079

Copyx = randn(4,1); //some random x input y = randn(4,1); //some random y input w = [10, 20, 30, 40]; //weight to be assigned to corresponding data point in the generated histogram, i.e. the pixel intensity value figure; H = histogram2(x,y); //Matlab built-in 2D histogram

geodome.m generates the vertices, adjacency graph and face list of a geodesic sphere. Apart from looking cool the vertices, or face centres, of a geodesic sphere can be useful for defining the bin centres of a 3D orientation histogram. gplot3d.m a 3D version of MATLAB's gplot function.

September 8, 2013 - Let's generate some synthetic data, which contains values and corresponding weights and find the weighted histogram. This trivial example demonstrate the usage of histwc function. One can adjust the bins as the third argument of the function. Posted by · msuzen at · 20:25 · Labels: data analysis, data manipulation, GNU Octave, MATLAB, statistics, weighted histograms ·
