To use default values for tol, n, or LineSpec, you can pass in the empty matrix ( ).įplot uses adaptive step control to produce a representative graph, concentrating its evaluation in regions where the function's rate of change is the greatest. No plot is drawn on the screen, however you can plot the function using plot(X,Y).Įnables you to pass parameters P1, P2, etc. Returns the abscissas and ordinates for ' function ' in X and Y.

The maximum step size is restricted to be (1/n)*(xmax-xmin).Īccepts combinations of the optional arguments tol, n, and LineSpec, in any order. With n >= 1 plots the function with a minimum of n+1 points. Plots ' function ' using the relative error tolerance tol and a line specification that determines line type, marker symbol, and color. Plots ' function ' using the relative error tolerance tol (The default is 2e-3, i.e., 0.2 percent accuracy). Plots ' function ' using the line specification LineSpec. X,Y fplot(fun,limits.) returns the abscissas and ordinates for fun in X and Y. In this video,you will learn about plotting a graph that is a function of x.fplot is the method of plotting functions into matlab which has been used in this. fplot(axeshandle.) plots into the axes with handle axeshandle instead of the current axes. MATLAB: Wont the code work with fplot fplot multiple figures I have everything figured out except I cant seem to get the fplot for my anonymous variable A to project over figure(2). For example, if f(x) returns then for input the function should return the matrix fplot(fun,lims.) accepts combinations of the optional arguments tol, n, and LineSpec, in any order. The function f(x) must return a row vector for each element of vector x. fplot uses adaptive step control to produce a representative graph, concentrating its evaluation in regions where the functions rate of change is the greatest. '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 ''.

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). 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). = plot(' function',limits,tol,n,LineSpec,P1,P2.)įplot plots a function between specified limits.
