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. Returns the abscissas and ordinates for ' function ' in x and Y. Plots ' function ' using the relative error tolerance tol and a line specification that determines line type, marker symbol, and color. The maximum number of x steps is (1/tol)+1. Plots ' function ' using the relative error tolerance tol (default is 2e-3).

' function ' is a name of a MATLAB M-file or a string containing the variable x. Plots ' function ' using the line specification LineSpec. limits is a vector specifying the x-axis limits ( ), or the x- and y-axis limits, ( ). Plots ' function ' between the limits specified by limits. 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). If the function returns more than one value for a given x, then y is a matrix whose. 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). 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). fplot plots a function between specified limits. Knowing that в€љx only exists for x в‰Ґ 0, see what occurs if you enter 4]).Fplot (MATLAB Function Reference) MATLAB Function ReferenceДescription fplot plots a function between specified limits. But I donВґt understand how the step size along the X-axis, for which the Y values are then calculated, becomes automatically defined or can be manually defined. Specify the interval as a two-element vector of the form xmin xmax. fplot step size MATLAB I try to understand the possibilities of FPLOT and consulted the documentation (relevant phrases cited below). fplot (f,xinterval): Plots the curve defined by function y f (x) in the specified interval. Remember that tan x is already stored in tan.m. Below are the various ways to plot an expression or a function in MATLAB: fplot (f): Plots the expression passed to it as a parameter. Define this function in an M-file and then use fplot to graph it for 0 в‰¤ t в‰¤ 5, find the two zeros, find its minimum value and evaluate the integral from 0 to 5 OP(t) dt.Д®xercise 2: Knowing that tan x has a vertical asymptote at x = ПЂ/2, see what occurs if you enter after the prompt 2]). % and y-coordinate of well as the graph, the following output should result:Д®xercise 1: Consider the output OP(t) = 1 в€’ 4eв€’t sin t for t в‰Ґ 0. X,Y fplot(fun,limits.) returns the abscissas and ordinates for fun in X and Y.

fplot(axeshandle.) plots into the axes with handle axeshandle instead of the current axes. This will graph the function for в€’10 в‰¤ x в‰¤ 10, find its zero (from the graph, between 0 and 1), find the x and y coordinates of the minimum and integrate the function from the x-intercept to x = 10. fplot(fun,lims.) accepts combinations of the optional arguments tol, n, and LineSpec, in any order. Now construct and execute the following M-file. This is not required for fplot, fzero or fminbnd.Д®xample: Consider the function f1(x) = x в€’ cos x / 2 + x 2. Hence the M-file func.m must use the array dot notation in the definition of func(x). Note: quadL uses arrays in its calculations.

or quadL(вЂ™func(x)вЂ™,a,b) finds an accurate value for the integral from a to be of func(x) dx.

fplot((x) sin(x)) This is really useful for getting a 'quick feel' for the shape of a function, or a family of functions.

or fminbnd(вЂ™func(x)вЂ™,a,b) finds the coordinates of a minimum point for a в‰¤ x в‰¤ b. Then fplot will use that function to draw a curve.

or fzero(вЂ™func(x)вЂ™,c) finds a root of the equation func(x) = 0 by commencing a search at x = c.

b]) or fzero(вЂ™func(x)вЂ™,) finds a root of the equation func(x) = 0 inside the interval providing func(a) and func(b) have opposite signs.

b]) or fplot(вЂ™func(x)вЂ™,) plots the function for a в‰¤ x в‰¤ b without requiring you to set up arrays.

Suppose a function y = func(x) has been defined in a function M-file func.m. I've read the MATLAB documentation for the fplot function but cannot make sense of it. Functions operating on functions: fplot, fzero, fminbnd, quadL fplot(f, 0, 4, 'black', 'LineWidth', 2), but this only gives me errors.
