how to use for loop for my issue



I have 2560 sample points. I want to calculate mean variance skewness

kurtosis for first 512 points, next 512 so on. so totally 5 sets of output

data .I want to plot 5 sets of values of mean , var , skew , kur in a

graph.

I read a data from excel consisting of 2560 points

x=xlsread('dta.xls');

i=1:512;

y=x(i)

m=mean(y);

v=var(y);

i=513:1024;

y=x(i)

m=mean(y);

v=var(y);

i=1025:1536

y=x(i)

m=mean(y);

v=var(y);

plot(m)

plot(v)

like this my code s going. I tried using for loop but I couldn't able to

make it.
