Hi I am new to matlab. I have a data set on a grid at 0.5 with x 141 y, 71 and x38. I am trying to get z scores for this multidimensional array. I used the code z=zscore(x) to get the z-scores which I got on the shape of 1*71*38. I want to end with a z-score per year instead of 2,698 values. Is there anyway I can get this?
Thanks in advance for your help.

If you started with an array of size 141x71x38, then zscore should have produced an array the same size,
>> X=rand(141,71,38);
>> Z=zscore(X);
>> whos X Z
Name Size Bytes Class Attributes
X 141x71x38 3043344 double
Z 141x71x38 3043344 double
I'm afraid I don't understand what your attachments mean either. matlab-z.mat contains what you got and yearz1.mat contains what you want to get? Why is year_z1 of dimensions 38x72 instead of 38x71? And which dimension of your arrays represent years?
