Substitute the array into the equation

x=[]

Set_data=3

while count < Set_data

y = [input('Input initial Pressure ')]

x=[y]

count=count+1;

end

Density=sqrt(y.*9.81)

y (and x) contains only the most recent input. To keep all inputs, you can do this:

count = 0;
x=[]
Set_data=3
while count < Set_data
  y = [input('Input initial Pressure ')]
  x(end+1)=y;
  count=count+1;
end
Density=sqrt(x.*9.81)
