how to convert a plot to a more accurate data?

Hello every body

I plotted a figure

now I want to have its matrix in high resolution (more points)

how can I do that?

clc;
clear;
close all;
x=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24];
y=[0,0,0,0,0.00332812794895371,0.497839135697320,1.98730498411229,3.68649138870512,5.26833130432260,6.65309642084821,7.52596016798571,7.87288100734659,7.72402047250485,7.03186688442338,6.01361607877631,4.65738228741286,3.07663320404878,1.46230367941451,0.221349612102121,0,0,0,0,0];
plot(x,y);

You need to create more points. Consider using the interp1 function. There are some helpful examples on the documentation page.
