how to sine wave plot

FPLOT Plot 2-D function FPLOT(FUN) plots the function FUN between the limits of the current axes, with a default of [-5 5]. FPLOT(FUN,LIMS) plots the function FUN between the x-axis limits specified by LIMS = [XMIN XMAX]. FPLOT(...,'LineSpec') plots with the given line specification. FPLOT(X,Y,LIMS) plots the parameterized curve with coordinates X(T), Y(T) for T between the values specified by LIMS = [TMIN TMAX]. H = FPLOT(...) returns a handle to the function line object created by FPLOT. FPLOT(AX,...) plots into the axes AX instead of the current axes. Examples: fplot(@sin) fplot(@(x) x.^2.*sin(1./x),[-1,1]) fplot(@(x) sin(1./x), [0 0.1]) If your function cannot be evaluated for multiple x values at once, you will get a warning and somewhat reduced speed: f = @(x,n) abs(exp(-1j*x*(0:n-1))*ones(n,1)); fplot(@(x) f(x,10),[0 2*pi]) See also FPLOT3, FSURF, FCONTOUR, FIMPLICIT, PLOT, FUNCTION_HANDLE.
