for t=1:1441
if 960<t<1150
EV1_6=Ci;
else
EV1_6=0;
end
I am trying to create a new array EV1_6 that will have the values from Ci while in the range of 960 to 1150 and fill the rest of the array with zeros. I need the zeros as this will be used for another task that simulates voltage.

if 960<t<1150
is not proper syntax for an if statement. You need
if 960<t && t<1150
See the documentation for details.
You also don't need a for loop:
EV1_6 = zeros(1,1441);
EV1_6(961:1149) = Ci;
will do the same thing, more efficiently.

OK, so do you mean that you want EV1_6 to be zero, except for the elements in that particular range, which should be copied over from Ci? In that case,
EV1_6 = zeros(1441,1);
EV1_6(961:1149) = Ci(961:1149);
