MATLAB: Help with standard deviation 3d matrix

3d matrixMATLABstandard deviationstdstd2

I have a 3D matrix of size (600 x 800 x 322) unit 16.

I would like to take the standard deviation of each 600 x 800 matrix — I am trying to get a result matrix size 1 x 1 x 322 containing the standard deviation of each matrix in this "stack".

I have tried using the std and std2 function, but haven't been able to get this to work.

Please help 🙂

stack_std = reshape(std( reshape( double(YourMatrix), [], size(YourMatrix,3) ) ), 1, 1, []);

MATLAB: Mean of Matrix Rows

The row means would be calculated as the mean of dimension 2.

Try this:

A = rand(5);
Anew = A - mean(A,2);
Check = mean(Anew,2)                    % Confirm: Mean = 0

MATLAB: A single line of MATLAB code that computes the mean and standard deviation of a 1‐dimensional array named A of numbers??

m=sum(x)/numel(x);  
s=sqrt(sum((x-m).^2)/(numel(x)-1));
