I am trying to calculate the standard deviation of 2D array 'v' of dimesnion 89 x 97.
I have tried as follows ,but it returns the output in the form of 1 x 97 instread of 89 x 97. Could someone help me with this
V1 = std (v);

The standard deviation of a scalar is 0 so the result is —
standard_deviation_v = zeros(size(v))
in this instance.
