The ranges of the bins are stored in an array of elements pointed to by range. This function returns the mean of the histogrammed variable, where the histogram is regarded as a probability distribution.

The range array should contain the desired bin limits. The library provides functions for reading and writing histograms to a file as binary data or formatted text. This function returns the contents of the ij -th bin of the histogram h.

It then reads numbers from stdinone line at a time, and adds them to the histogram. gsp

It can be shown that by taking a uniform random number in this range and finding its corresponding coordinate in the cumulative probability distribution we obtain samples with the desired probability distribution. You would also need to provide the Apple-provided libc on the Linux system.

It’s been a while. This function returns the covariance of the histogrammed x and y variables, where the histogram is regarded as a probability distribution. So you would need the Apple-provided ld.

The functions for accessing the histogram through coordinates use a binary search to identify the bin which covers the appropriate range.

The algorithm used to compute the sample is given by the following formula. The ranges can be arbitrary, subject to the restriction that they are monotonically increasing. If x lies in the valid range gdl the histogram then the function returns zero to indicate success.

The bin is located using a binary search. It would be easier to run: In this equation is the number of events in the bin which containsis the area of the bin and is the total number of events.

The search includes an optimization for histograms with uniform ranges, and will return the correct bin immediately in this case. Each bin is inclusive at the lower end and exclusive at the upper end. Email Required, but never shown. However the particular one is Gnuplot.

This is the number of histogram bins used to approximate the probability distribution function in the x and y directions. The search includes an optimization for histograms with uniform range, and will return the correct bin immediately in this case.

The function returns 0 to indicate success. If the point lies inside the valid ranges of the histogram then the function returns zero to indicate success. You can histkgram the bins of a two-dimensional histogram either by specifying a pair of coordinates or by using the bin indices directly.

This function finds the indices of the bin containing the maximum value in the histogram h and stores the result in ij. If you want to include these values for the side bins you will need to add an extra row or column to your histogram. On the left-hand side of each bin the square bracket [ denotes an inclusive lower boundand the round parentheses on the right-hand side denote an exclusive upper bound. This function copies the histogram src into the pre-existing histogram destmaking dest into an exact copy of src.

This function multiplies the contents of the bins of histogram h1 by the contents of the corresponding bins in histogram h2i.

The bin ranges are shown in the table below. I was just updating my answer. For example a detector might record both the position of an event and the amount of energy it deposited.
