How can i convert this R code into MATLAB

The code is as follows

ef=function(x)
{
r=rnorm(10000,0,1/sqrt(2))
v=ifelse(r<=x & r>=0,1,0)
e=2*(sum(v)/length(r))
return(e)
}

[Basil C.]

The rnorm function can be replaced by

r = normrnd(0,1/sqrt(2),[1,1000])

You can read more about it: normrnd

If else statement should be much of a problem if you know the basics of Matlab

[Walter Roberson]

r = normrnd(0,1/sqrt(2),[1,1000])
e = 2 * mean(r>=0 & r<=x);

The code expects scalar x.

It seems a bit odd to simulate it instead of calculating normcdf()
