Hi,

there is a strange behavior when combining the 'sd' function with matrices:
1) I thought it flags an error - is it now allowed for matrices?
2) the result is not correct, but the 'var' function works with this simple matrix in the example

<hansl>
matrix test = {-0.08142857;0.05560000}
eval mcov(test)
eval var(test)
eval sqrt(mcov(test))
eval sqrt((test[1]-mean(test))^2 + (test[2]-mean(test))^2)
eval sd(test)
<hansl>

Best
