J = besselj (nu,Z,scale) specifies whether to exponentially scale the Bessel function of the first kind to avoid overflow or loss of accuracy. If scale is 1, then the output of besselj is scaled by the factor exp (-abs (imag (Z))). fill (X1,Y1,C1,...,Xn,Yn,Cn) plots multiple two-dimensional filled polygonal regions on the same axes. example. fill ( ___,Name,Value) modifies the patches using one or more name-value arguments to set properties. Patches can be specified using any of the input argument combinations in previous syntaxes.Function to plot, specified as a function handle to a named or anonymous function. Specify a function of the form y = f(x). The function must accept a vector input argument and return a vector output argument of the same size. Use array operators instead of matrix operators for the best performance. For example, use .* (times) instead of ...Plot Single Data Series. Create a stem plot of 50 data values between - 2 π and 2 π. figure Y = linspace (-2*pi,2*pi,50); stem (Y) Data values are plotted as stems extending from the baseline and terminating at the data value. The length of Y automatically determines the position of each stem on the x -axis.Rectangular Pulse Function. If a < x < b, then the rectangular pulse function equals 1. If x = a or x = b and a <> b, then the rectangular pulse function equals 1/2. Otherwise, it equals 0. The rectangular pulse function is also called the rectangle function, boxcar function, Pi function, or gate function.The heaviside function returns 0, 1/2, or 1 depending on the argument value. If the argument is a floating-point number (not a symbolic object), then heaviside returns floating-point results. Evaluate the Heaviside step function for a symbolic input sym (-3). The function heaviside (x) returns 0 for x < 0. H = heaviside (sym (-3)) H = 0.plot of inverse laplace of a function.
