Fplot Ezplot
Ezplot (f) plots the expression f (x) over the default domain -2π f (x) is an explicit function of only x. Where as, fplot (f) plots the curve defined by the function y = f (x) over the default interval -5 5 for x. We can plot the curve over some specified interval as well. The function fplot also generates two-dimensional plots with linear axes using a function name and limits for the range of the x-coordinate instead of the x and y data. For example, fplot (@sin, -10, 10, 201). H = ezplot Plot the 2-D curve defined by the function f. Ezplot (f) plots a symbolic expression, equation, or function f. By default, ezplot plots a univariate expression or function over the range –2π 2π or over a subinterval of this range. If f is an equation or function of two variables, the default range for both variables is –2π 2π or over a subinterval of this range. Ezplot (f) plots the expression f (x) over the default domain -2π Where as, fplot (f) plots the curve defined by the function y = f (x) over the default interval -5 5 for x. We can plot the curve over some specified interval as well. Here the curve is defined implicitly by f(x, y) 0, but we do not enter the 0 part. See help for the (non-symbolic) ezplot, which this routine calls after trying to convert sym inputs to anonymous functions. Using sym arguments for dom and n can lead to ambiguity where OctSymPy cannot tell if you are specifying n or f2.For example.

Details
Calculates the x, y coordinates of points to be plotted and calls the plot function.
If fill is TRUE, also calls the polygon function with the x, y coordinates in appropriate order.
If the no. of markers is greater than 2, this number of markers will be added to the curve, with equal distances measured along the curve.
Ezplot Plot
Value
- Plots the function graph and invisibly returns
NULL.Note
fplot is almost an alias for ezplot as all ez... will be replaced by MATLAB with function names f... in 2017.
Fplot Ezplot
ezplot should mimick the Matlab function of the same name, has more functionality, misses the possibility to plot several functions.
