ezplot(fun) plots the expression fun(x) over the default domain -2π < x < 2π, where fun(x) is an explicit function of only x.
fun can be a function handle, a character vector, or a string.
ezplot(fun,[xmin,xmax]) plots fun(x) over the domain: xmin < x < xmax.
Fplot generates one plot line per output column, from a vector input. Ezplot with 2 variables generates an implicit plot of the expression evaluating to 0. Sign in to answer this question.
*This will plot the cosine and sine functions and label them accordingly in the legend. If the first argument hax is an axes handle, then plot into this axes, rather than the current axes returned by gca. The optional return value h is a vector of graphics handles to the created line objects. To save a plot, in one of several image formats such as PostScript or PNG, use the print command.
*H = ezplot(fun,minValue maxValue); This will plot fun(x) over the domain minValue EZPLOT will use the default -2.pi 2.pi. EZPLOT returns a handle(s) to the line objects that are plotted (h in the above code).Fplot Ezplot
For an implicit function, fun2(x,y):
ezplot(fun2) plots fun2(x,y) = 0 over the default domain -2π < x < 2π, -2π < y < 2π.
ezplot(fun2,[xymin,xymax]) plots fun2(x,y) = 0 over xymin < x < xymax and xymin < y < xymax.
ezplot(fun2,[xmin,xmax,ymin,ymax]) plots fun2(x,y) = 0 over xmin < x < xmax and ymin < y < ymax.
ezplot(funx,funy) plots the parametrically defined planar curve funx(t) and funy(t) over the default domain 0 < t < 2π.
ezplot(funx,funy,[tmin,tmax]) plots funx(t) and funy(t) over tmin < t < tmax.
ezplot(...,fig) plots into the figure window identified by fig. Use any of the input argument combinations in the previous syntaxes that include a domain. The domain options are [xmin xmax], [xymin xymax], [xmin xmax ymin ymax], and [tmin tmax].
ezplot(ax,...) plots into the axes ax instead of the current axes (gca).
h = ezplot(...) returns either a chart line or contour object.

Octave can plot a function from a function handle, inline function, orstring defining the function without the user needing to explicitlycreate the data to be plotted. The function fplot also generatestwo-dimensional plots with linear axes using a function name and limitsfor the range of the x-coordinate instead of the x and y data. Forexample,
produces a plot that is equivalent to the one above, but also includes alegend displaying the name of the plotted function.: fplot(fn, limits): fplot(…, tol): fplot(…, n): fplot(…, fmt): [x, y] =fplot(…)
Plot a function fn within the range defined by limits.
fn is a function handle, inline function, or string containing thename of the function to evaluate.
The limits of the plot are of the form [xlo, xhi] or[xlo, xhi, ylo, yhi].
The next three arguments are all optional and any number of them may begiven in any order.
tol is the relative tolerance to use for the plot and defaultsto 2e-3 (.2%).
n is the minimum number of points to use. When n is specified,the maximum stepsize will be (xhi - xlo) / n. Morethan n points may still be used in order to meet the relativetolerance requirement.
The fmt argument specifies the linestyle to be used by the plotcommand.
If the first argument hax is an axes handle, then plot into this axes,rather than the current axes returned by gca.
With no output arguments the results are immediately plotted. With twooutput arguments the 2-D plot data is returned. The data can subsequentlybe plotted manually with plot (x, y).
Example:
Programming Notes:
fplot works best with continuous functions. Functions withdiscontinuities are unlikely to plot well. This restriction may be removedin the future.
fplot requires that the function accept and return a vector argument.Consider this when writing user-defined functions and use .*,./, etc. See the function vectorize for potentiallyconverting inline or anonymous functions to vectorized versions.

Other functions that can create two-dimensional plots directly from afunction include ezplot, ezcontour, ezcontourf andezpolar.: ezplot(f): ezplot(f2v): ezplot(fx, fy): ezplot(…, dom): ezplot(…, n): ezplot(hax, …): h =ezplot(…)
Plot the 2-D curve defined by the function f.
The function f may be a string, inline function, or function handleand can have either one or two variables. If f has one variable, thenthe function is plotted over the domain -2*pi < x < 2*piwith 500 points.
If f2v is a function of two variables then the implicit functionf(x,y) = 0 is calculated over the meshed domain-2*pi <= x | y <= 2*pi with 60 points in each dimension.
For example:
If two functions are passed as inputs then the parametric function
is plotted over the domain -2*pi <= t <= 2*pi with 500 points.
If dom is a two element vector, it represents the minimum and maximumvalues of both x and y, or t for a parametric plot. Ifdom is a four element vector, then the minimum and maximum values are[xmin xmax ymin ymax].Fplot Vs Ezplot
n is a scalar defining the number of points to use in plottingthe function.
If the first argument hax is an axes handle, then plot into this axes,rather than the current axes returned by gca.

f is a string, inline function, or function handle with two argumentsdefining the function. By default the plot is over the meshed domain-2*pi <= x | y <= 2*pi with 60 points in each dimension.
