2fplot
Purpose Plot a function between specified limits
Syntax fplot(function,limits)
fplot(function,limits,LineSpec)
fplot(function,limits,tol)
fplot(function,limits,tol,LineSpec)
fplot(function,limits,n)
fplot(axes_handle,...)
[X,Y] = fplot(function,limits,...)
[...] = fplot(function,limits,tol,n,LineSpec,P1,P2,...)
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(function,limits) plots 'function' between the limits specified by
limits. limits is a vector specifying the x-axis limits ([xmin xmax]), or the x-
and y-axis limits, ([xmin xmax ymin ymax]).
function 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
f1(x1) f2(x1) f3(x1)
f1(x2) f2(x2) f3(x2)
fplot(function,limits,LineSpec) plots 'function' using the line
specification LineSpec.
