clear 
close all
zai=[ 0.0 0.4 0.2 0.3 0.4]; %I  want to change the size of this array based on inputting the size value and I will give the n number of values.
beta=0:0.005:4;
for i=1:length(zai)
for j=1:length(beta)
d(i,j)=(1/((1-beta(j)^2)^2+(2*beta(j)*zai(i))^2))^0.5;

%zai=[ 0.0 0.4 0.2 0.3 0.4]; %I  want to change the size of this array based on inputting the size value and I will give the n number of values.
str = input("Enter N numbers: ", "s");
zai = sscanf(str, '%f');

beta=0:0.005:4;
for i=1:length(zai)
for j=1:length(beta)
d(i,j)=(1/((1-beta(j)^2)^2+(2*beta(j)*zai(i))^2))^0.5;
end

Did you try this code? Did you notice how it might be possible to use these functions for what you describe?
