IF statement problem in creating an array with zeros

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.

when I try

EV1_6 = zeros(1,1441); EV1_6(961:1149) = Ci;

it results in an error "In an assignment A(:) = B, the number of elements in A and B must be the same."

What is the size of Ci? From your prior syntax, I assumed it was a scalar.

[Dave Griffin]

Ci is 1441x1 double

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);
