I have a range of values, x = 0:0.1:5 as my inputs.
I want to use
Eq.1 when 0 < x <= 1,
and
Eq.2 for 1 < x < 5.
and then plot(x,y)
if (x >= 0) && (x <= 1)
y = x^(0.5)
elseif (x > 1)
y = x^(-0.5)
end

Is your Eq1: y = x^(0.5) and Eq2: y = x^(-0.5)? Also, what are the specific bounds? The code snippet at the end has different bounds than the two initial bounds you stated

The following should work for your intended restrictions.
% initialize x
x = 0:0.1:5;
% initialize y with all zeros
y = zeros(1,numel(x));
for i = 1:numel(x)
if (x(i) >= 0) && (x(i) <= 1)
y(i) = x(i)^0.5;
else
y(i) = x(i)^(-0.5);
end
end
plot(x,y)
