The bins can use arbitrary sets of ranges uniformly spaced bins are the default.

The functions for allocating memory to a 2D histogram follow the style of malloc and free.

gsl-histogram(1) – Linux man page

A histogram consists of a set of bins which count the number of events falling into a given range of a continuous variable. The functions for allocating memory to a histogram follow the style of malloc and free. This function subtracts the contents of the bins in histogram h2 from the corresponding bins of histogram h1i.

This function reads formatted data from the stream stream into the histogram h. This function resets all the bins of the histogram h to zero. The bin is located using a binary search. This function returns 1 if the all of the individual bin ranges of the two histograms are identical, and 0 otherwise. The distribution of events within each bin is assumed to be uniform. Another possibility is to form a joint distribution by recording related variables.

Furthermore, the object files from OS X will be linked against the Apple-supplied libcand require the corresponding symbols from the Apple-supplied library.

The lower limit is inclusive i.

The functions return 0 to indicate success. Header states merely the interface that is exposed by this library. Using a higher resolution grid we can see the original underlying histogram and also the statistical fluctuations caused by the events being uniformly distributed over the area of the original bins.

You can access the bins of a two-dimensional histogram either by specifying a pair of coordinates or by hisrogram the bin indices directly. This function multiplies the contents of the bins of histogram h1 by the contents of the corresponding bins in histogram h2i. The library provides functions for reading and writing histograms to a file as binary data or formatted text.

If the point lies inside hitsogram valid ranges of the histogram then the function returns zero to indicate success. The bins are floating-point numbers, so you can increment them by non-integer values if necessary. Negative bin values are ignored for the purposes of this calculation. histograk

Histograms — GSL documentation

This function sets the ranges of the existing histogram h using the arrays xrange and yrange of size xsize and ysize respectively. The additional element is required for the upper value of the final bin. This function returns the index of the bin containing the maximum value. In this picture the values of the range array are denoted by.

This function returns the mean of the histogrammed y variable, where the histogram is regarded as a probability distribution. It would be easier to run: Regarding the second question, I’ll update the posting above. This function finds the indices of the bin containing the minimum value in the histogram h and stores the result in ij.

The histogram output is formatted in three columns, and hstogram columns are separated by spaces, like this: This function reads into the histogram h from the stream stream in binary format.

The bin ranges are shown in the table below. So there are surely a lot of libraries out there. This function finds and sets the indices i and j to the bin which covers the coordinates xy. This function frees the histogram h and all of the memory associated with it.

The search includes an optimization for histograms with uniform ranges, and will return the correct bin immediately in this case. The library provides efficient routines for selecting random samples from probability distributions. However the particular one is Gnuplot. This function returns a pointer to a newly created histogram which is an exact copy of the histogram src. This function frees the 2D histogram h and all of the memory associated with it.

The ranges of the bins are stored in an array of elements pointed to by range. Sign up using Facebook. These functions find the upper and lower range limits of the i -th and j -th bins in the x and y directions of the histogram h. Histograms provide a convenient way of summarizing the distribution of a set of data. Negative bin values are included in the sum.

This function writes the ranges and bins of the histogram h to the stream stream in binary format. This function returns 1 if all the individual bin ranges of the two histograms are identical, and 0 otherwise.
