Dummies has always stood for taking on complex concepts and making them easy to understand. Dummies helps everyone be more knowledgeable and confident in applying what they know. Directly by specifying the titles to the plotting function (ex: plot ). In this case titles are modified during the creation of plot. The title function can also be used. It adds titles on an existing plot. This article describes how to add and change a main title, a subtitle and a caption to a graph generated using the ggplot2 R package. We’ll show also how to center the title position, as well as, how to change the title font size and color. In this R graphics tutorial, you will learn how to: Add titles and subtitles by using either the function ggtitle or labs. MATLAB function fplot is used to generate symbolic plots with respect to expressions or functions. The default range of interval for the graph generated out of the fplot function is -5,5.

Plot a function between specified limits

Syntax

Description

fplot plots a function between specified limits. The function must be of the form y = f(x), where x is a vector whose range specifies the limits, and y is a vector the same size as x and contains the function's value at the points in x (see the first example). If the function returns more than one value for a given x, then y is a matrix whose columns contain each component of f(x) (see the second example).

fplot(fun,limits)plots fun between the limits specified by limits. limits is a vector specifying the x-axis limits ([xminxmax]), or the x- and y-axes limits, ([xminxmaxyminymax]).

fun must be

• The name of an M-file function
• A string with variable x that may be passed to eval, such as 'sin(x)', 'diric(x,10)', or '[sin(x),cos(x)]'
• A function handle for an M-file function or an anonymous function (see Function Handles and Anonymous Functions for more information)

The function f(x) must return a row vector for each element of vector x. For example, if f(x) returns [f1(x),f2(x),f3(x)] then for input [x1;x2] the function should return the matrix

fplot(fun,limits,LineSpec)plots fun using the line specification LineSpec.

fplot(fun,limits,tol)plots fun using the relative error tolerance tol (the default is 2e-3, i.e., 0.2 percent accuracy).

fplot(fun,limits,tol,LineSpec)plots fun using the relative error tolerance tol and a line specification that determines line type, marker symbol, and color. See LineSpec for more information.

fplot(fun,limits,n)with n >= 1 plots the function with a minimum of n+1 points. The default n is 1. The maximum step size is restricted to be (1/n)*(xmax-xmin).

fplot(fun,lims,...) accepts combinations of the optional arguments tol, n, and LineSpec, in any order.

fplot(axes_handle,...)plots into the axes with handle axes_handle instead of the current axes (gca).

[X,Y] = fplot(fun,limits,...)returns the abscissas and ordinates for fun in X and Y. No plot is drawn on the screen; however, you can plot the function using plot(X,Y).

Remarks

fplot uses adaptive step control to produce a representative graph, concentrating its evaluation in regions where the function's rate of change is the greatest.

Examples

Plot the hyperbolic tangent function from -2 to 2:

Create an M-file, myfun, that returns a two-column matrix:

Create a function handle pointing to myfun:

Plot the function with the statement

Addition Examples

This example passes function handles to fplot, one created from a MATLAB function and the other created from an anonymous function.
