The idea of hist function is similar to stacks of coins: Let's say you have a bag of coins and after you separate them by values and stack on one another, you will get different heights. The hist function does the same. data= [1 3 5 7 4 8 0 1 3];

X = ifft2(Y) returns the two-dimensional discrete inverse Fourier transform of a matrix using a fast Fourier transform algorithm.If Y is a multidimensional array, then ifft2 takes the 2-D inverse transform of each dimension higher than 2. The output X is the same size as Y. The matlab code to solve the above form is: % Code to solve a second order 2D Heat conduction PDE % d^2T/dx^2 + d^2T/dy^2 = 0 % BC % Left, T=400K % Right, T=800K % Top, T=600K % Bottom, T=900K clear all;close all;clc nx =11; ny =11; % Step size in x and y direction is same.

A histogram is a graphical representation used to estimate the probability distribution of a variable. This video help in 2-D histogram plot using matlab I am wondering if there is any build in function or an easy way to plot a histogram of elements of a 2d array. For example, if A=rand(100,1), then A is an 1D array, and hist(A) can do the histogram. However, what if A=rand(100,100), and I would like to make a histogram on elements of A, just like treating each element in A as an element on a 1D function [ result ] = Hist2D (vec0, vec1) %Hist2D takes two vectors, and computes the two dimensional histogram % of those images.
