how to plot the vrr functions vrr,3,5,2

% plot Vrr
qvrr = quiver3(RP(1),RP(2),RP(3), vrr,3,5,2,"g"); % vector vrr
qvrr.DisplayName="vrr";
%text(vrr,"Vrr",Color='g')
disp(vrr);

what is vrr,3,5,2 in this context?

[Adalberto]

vrr é um vector que determina a potencia recebida.ou seja pretendo determinar a potencia recebida. e o 3,5,2 são as cordenadas destino para o plot da função. gostaria de saber se ao inves de utilizar 3,5,2 o que devo usar para a saida do plot?

gostaria de saber também como faço para pedir ao utilizador a introdução dos valores dos parametros de entrada automaticamente numa determinada função?

If you are calculating received electrical potential at the point with coordinates (3,5,2) then that would be a single point, and you would not use quiver3() to plot a single point. It is not obvious to me that the received electrical potential is a vector-valued quantity that you would use quiver plots for -- not unless you happened to have two or three sources of energy and were plotting the contribution from each of the sources.

I am assuming that here “vrr” is referring to Valence-Rydberg-Rydberg (VRR) contraction functions which is used in quantum calculations.

The following code can be used to plot the “vrr,3,5,2” in MATLAB:

% Define the range of x values for the plot
x = linspace(-1, 1, 100);

% Compute the VRR function values for each angular momentum
vrr_3_5_2 = zeros(size(x));
vrr_3_5_2(x >= 0) = x(x >= 0).^3 .* exp(-x(x >= 0)/2);
vrr_3_5_2(x < 0) = -1/3 * x(x < 0).^2 .* (2*x(x < 0).^2 - 15*x(x < 0) + 35) .* exp(x(x < 0)/2);

% Plot the VRR function values
plot(x, vrr_3_5_2, 'LineWidth', 2);
xlabel('x');
ylabel('VRR_{3,5,2}(x)');
title('Plot of VRR_{3,5,2}(x)');
grid on;

This code defines the range of x values for the plot, and then computes the VRR function values for each angular momentum using the formulas for VRR,3,5,2. The computed values are then plotted using the plot function, and the plot is labelled with axis labels and a title.
