The built-in function in a MATLAB for the standard deviation is known as std; the standard deviation can be found either as the sqrt of the variance, or by using std:

>> shortx = [2 5 1 4];

>> myvar = var(shortx)

myvar =

    3.3333

>> sqrt(myvar)

ans =

    1.8257

>> std(shortx)

ans =

    1.8257
