matlab - retrieve data at specific loop values -

-

i wondering how achieve following: have vector (scalar) called timesteps. timesteps increments according length of vector (nbins_max) set @ fixed length (but may change occasionally). declare 5 full system rotations use: 

timesteps = 5*nbins_max;

i retrieve data each rotation of system. in pseduo-code i'm looking achieve following:

where timesteps = each multiple of nbins_max retrieve data end

i set manually @ each number of timesteps i'm interested in, however, due number of rollers in of systems prove tedious , potentially error prone! also, timesteps varies considerably in it's range, 1*nbins_max, 1000*nbins_max, perhaps more this!

any pointers or general appreciated! reading

richard

the modulus 0 @ each multiple of nbins_max:

where mod(timesteps, nbins_max)==0     retrieve data end

hope helps?
