How to write a script to fill vector

Write a script to fill vector b defined by b = {x for x<1 & x^2 for 1≤x≤4 & 16 for x>4}

First fill in vector x from 0 to 5 in intervals of 0.5 and then using a for loop with if, elseif and/or else statements, fill in vector b based on x as specified above. Print the value of b when finished.

Hi,

I understand that you want to create a vector b with the conditions as defined using for / if / else statements.

There are two ways to create the vector b as specified.

%way 1 using loop and other statements 
x = [0:0.5:5.0]  
b = [];  
for i=1:numel(x)  
if(x(i)<1)  
b = [b,x];  
elseif(x(i)>=1 && x(i)<=4)  
b = [b,x(i)^2];  
else  
b = [b,4];  
end  
end  
b  

%way 2 
x = [0:0.5:5.0];  
b = [X(X<1), (X(X>=1 & X<=4)).^2 ];  
k = x(x>4);  
k(:,:) = 4;  
b = [b,k]
