Matlab的hist函数 hist有直方图的意思，直方图也被称为频数直方图，它用来显示数据集的分布情况。在MATLAB中绘制直方图的函数是hist，用法是hist（y，x），表示以向量x的各个元素为统计范围，绘制y的分布情况。

Note that it is a third-party function, so you will need to download it and put in on your MATLAB path or in the current directory. The download button is in the top right corner, labelled "Download Zip". If Xq and Yq are vectors of the same size and orientation, then Xq and Yq are treated as scattered points in 2-D space. If Xq and Yq are matrices, then they represent either a full grid of query points (in meshgrid format) or scattered points. If Xq and Yq are N-D arrays, then … MATLAB hist() A histogram is a plot presenting the distribution of values within a data set. To develop a histogram, the range of values within the data set is split into evenly spaced bins, and the number of data values falling into each bin is determined.
X = randi ( [-5,5],100,1); [N,edges,bin] = histcounts (X, 'BinMethod', 'integers' ); Find the bin count for the third bin by counting the occurrences of the number 3 in the bin index vector, bin. MATLAB supports plotting histogram feature that enables the user to create a bar graph for any vector or matrix and grouping the data into bins using an automatic binning algorithm.
Projektet syftar till att med hjälp av matlab-simulering utreda möjligheten att skydda månbasen och dess personal från kosmisk strålning Figure 6. Histogram for the test image one-dimensional DCT applied two times for the 2D- transform.
If xbins is a vector of evenly spaced values, then hist uses the values as the bin centers. If xbins is a vector of unevenly spaced values, then hist uses the midpoints between consecutive values as the bin edges. Histogram on elements of a 2D matrix in Matlab.
hist は推奨されません。 代わりに histogram を使用してください。. コードの更新に関する提案も含め、詳細は推奨されない hist および histc インスタンスの置き換えを参照してください。

Basic 2D plots, good 3D graphics, and even animation possibilities are available in an easy environment.The most basic and useful command for producing simple 2D plots is By doing 'tic-tocs' I found out that these precise lines were taking up 90% of the execution time. Is there any way to have access to the histogram data without opening a figure, or any other way of optimizing time ?

HIST2D (X,Y,Xedges,Yedges) specifies the edges of the bins in each dimension using the vectors Xedges and Yedges. HIST2D (,'tile') plots the result as a tiled 2-D image. HIST2D (,'bar3') plots the result as a 3-D bars. MATLAB hist() A histogram is a plot presenting the distribution of values within a data set. To develop a histogram, the range of values within the data set is split into evenly spaced bins, and the number of data values falling into each bin is determined.

Here we discuss How to Create a circle using Rectangle Function, a Solid 2D Circle, a Circle in MATLAB and Simple arc. Y = fft2(X) returns the two-dimensional Fourier transform of a matrix using a fast Fourier transform algorithm, which is equivalent to computing fft(fft(X).').'.If X is a multidimensional array, then fft2 takes the 2-D transform of each dimension higher than 2. The output Y is the same size as X. Learn MATLAB and Simulink Tutorials and courses to advance your skills, whether you're a beginner or expert user.
