Fplot Limit
PlotPub Publication quality graphs in MATLAB. MATLAB is an excellent tool. It is equally popular among students, researchers and professors. If you use MATLAB for your project/research, you probably know that it is not easy to create publication quality graphs (PQGs) using MATLAB. FPLOT Plot function. FPLOT(FUN,LIMS) plots the function FUN between the x-axis limits. Specified by LIMS = XMIN XMAX. Using LIMS = XMIN XMAX YMIN YMAX also controls the y-axis limits. FUN(x) must return a row vector for. Each element of vector x. For example, to plot the function y=exp(x) for x=0 to 10 with the increment = 1. Fplot (@(x) was used to generate a figure the resulting curve shape is wrong and errors are produced. The correct X minimum and maximum values were not represented correctly. My command Used was taken from the 'help' menu.

How to control the limits of data values in R plots. R has multiple graphics engines. Here we will talk about the base graphics and the ggplot2 package. We’ll create a bit of data to use in the examples: one2ten. The fundamental idea in calculus is to make calculations on functions as a variable “gets close to” or approaches a certain value.

fplotPlot 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('plots function',limits)'function' between the limits specified by limits. limits is a vector specifying the x-axis limits ([xminxmax]), or the x- and y-axis limits, ([xminxmaxyminymax]).
'function' must be the name of an M-file function or a string with variable x that may be passed to eval, such as 'sin(x)', 'diric(x,10)' or '[sin(x),cos(x)]'.
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('plots function',limits,LineSpec)'function' using the line specification LineSpec.
fplot('plots function',limits,tol)'function' using the relative error tolerance tol (The default is 2e-3, i.e., 0.2 percent accuracy).
fplot(plots 'function',limits,tol,LineSpec)'function' using the relative error tolerance tol and a line specification that determines line type, marker symbol, and color.
fplot('with function',limits,n)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.
[X,Y] = fplot('returns the abscissas and ordinates for function',limits,...)'function' in X and Y. No plot is drawn on the screen, however you can plot the function using plot(X,Y).
[...] = plot('enables you to pass parameters function',limits,tol,n,LineSpec,P1,P2,...)P1, P2, etc. directly to the function 'function':
To use default values for tol, n, or LineSpec, you can pass in the empty matrix ([]).
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:
