MATLAB: Representation of array

m-fileMATLABsimulink

there is a vector T=[ 0 .00001 ………… .0001 ]
and the corresponding value at different times are represented by: Y=[ 1 2 ……….. 3 ] now if i want to track the value of Y at time T=.00001; then how will i get that? actually in sim(0 command the values are being produced for different times. how to pick up a perticular value at a perticular time?

Like this example?
>> T = 0 : 0.01 : 0.05
T =
         0    0.0100    0.0200    0.0300    0.0400    0.0500
>> Y = rand(size(T))
Y =
    0.9493    0.3479    0.4887    0.3533    0.7126    0.2021
>> Y_track = Y(T == 0.02)
Y_track =
    0.4887
I think there is a better way to do this... since equalities for floating point numbers are generally not good programming practice due to precision issues.
