Graphs are a primary method of visualisation and analysis. MATLAB makes it possible to plot graphs separately and also plot multiple lines in the same plot.

Matlab can be used efficiently to plot various types of 2D and 3D graphs for different set of equations and functions.

Matlab automatically creates axes for a histogram and resizes them as you resize the graph, but you also have options to change the axes manually.

This paper has two major parts. In the first part histogram equalization for the image enhancement was implemented without using the built-in function in MATLAB. Here, at first, a color image of a rat ...
