This gwl the natural quantity for generating samples via the inverse transform method, because there is a one-to-one mapping between the cumulative probability distribution and the range [0,1].

Once a histogram has been created it can also be converted into a probability distribution function. A probability distribution function is defined by the following struct, which actually stores the cumulative probability distribution function. This function returns the standard deviation of the histogrammed variable, where the histogram is regarded as a probability distribution. The probability distribution function for a histogram consists of a set of bins which measure the probability of an event falling into a given range of a continuous variable.

If x lies in the valid range of the histogram then the function returns zero to indicate success. This function multiplies the contents of the bins of histogram h by the constant scalei.

It’s been a while.

This function returns the standard deviation of the histogrammed y variable, where the histogram is regarded as a probability distribution.

The counts for each bin are stored in an array of n elements pointed to by bin. If you want to include this value for the last bin you will need to add an extra bin to your histogram. In the case where several bins contain the same maximum value the first bin found is returned.


The following functions are used by the access and update routines to locate the bin which corresponds to a given coordinate. In the sgl where several bins contain the same maximum value the smallest index is returned. This function finds the indices of the bin containing the minimum value in the histogram h and stores the result in ij.

GNU Scientific Library – Reference Manual: Histograms

The library provides efficient routines for selecting random samples from probability distributions. The two histograms must have identical bin ranges. The histogram h must be preallocated with the correct lengths since the function uses the sizes of h to determine how many numbers to read. This function resets all the bins in the histogram h to zero. This function uses two uniform random numbers between zero and one, r1 and r2to compute a single random sample from the two-dimensional probability distribution p.

This chapter describes functions for creating histograms. This function uses ra uniform random number between zero and one, to compute a single random sample from the probability distribution p. Since the upper limits of the each bin are the lower limits of the neighboring bins there is duplication of these values but this allows the histogram to be manipulated with line-oriented tools.

This function initializes the probability distribution p with the contents of the histogram h.

The histogram output is formatted in five columns, and the columns are separated by spaces, like this:. The values of the histogram bins are reset to zero. This function subtracts the contents of the bins in histogram h2 from the corresponding bins of histogram h1i.

This function finds the upper and lower range limits of the i -th bin of the histogram h. This function sets the ranges of the existing histogram h using the arrays xrange and yrange of size xsize and ysize respectively. As in the one-dimensional case, a two-dimensional histogram made by counting events can be regarded as a measurement of a probability distribution. This function copies the histogram src into the pre-existing histogram destmaking dest into an exact copy of src. Each bin is inclusive at the lower end and exclusive at the upper end.


gsl-histogram(1) – Linux man page

The program takes three arguments, specifying the upper and lower bounds of the histogram and the number of bins. This is the number of histogram bins used to approximate the probability distribution function in the x and y directions. Note that the size of the range array should be defined to be one element bigger than the number of bins.

So I think the you’d better just install it on your machine. Mathematically this means that the bins are defined by the following inequality.

This function returns the standard deviation of the histogrammed x variable, where the histogram is regarded as a probability distribution.

It then reads numbers from stdinone line at a time, gel adds them to the histogram. The bin ranges are shown in the table below. Email Required, but never shown. The function returns 0 to indicate success.

However the particular one is Gnuplot. This function writes the ranges and bins of the histogram h to the stream stream in binary format.
