std in NDArrays

[Hugo Neto]

Dear All,

 

I'm facing another problem with the std (Standard Deviation) function. Because i have a three dimensional array and i would like to do a std in it along the 3º dimension.

 

For instance in Matlab:

 

realstate=std(state,0,3);        % std deviation along dimension 3

 

This will store in realstate variable the standard deviation on the 3º dimension

 

In Octave i reach the following statement:

 

"error: invalid conversion of NDArray to Matrix"

 

I guess that this function is not yet implemented with NDArray option in 2.1.57 Octave version. Do you know that?

 

Any solution to surpass this problem?

 

Thanks a lot,

 

Regards,
