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. fplot ( ,LineSpec) specifies the line style, marker symbol, and line color. Specify the interval as a two-element vector of the form tmin tmax.

fplot (funx,funy,tinterval) plots over the specified interval. 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. fplot (funx,funy) plots the curve defined by x funx (t) and y funy (t) over the default interval -5 5 for t. 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. For example, if f(x) returns then for input the function should return the matrix The function f(x) must return a row vector for each element of vector x. '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, ( ). 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 functions value at the points in x (see the first example). Plots ' function ' between the limits specified by limits. fplot plots a function between specified 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.
