How to calculate correlation coefficient and p-value between two 3-d matrix?

Hello,

I have two gridded matrix having latitude,longitude and time(180x360x12). I have calculated correlation coefficient between both matrices using following: http://in.mathworks.com/matlabcentral/answers/15884-correlation-for-multi-dimensional-arrays

now I want to find p-value (0.05) for each grid cell. than I want to set correlation values in matrix in three part: one will show positively significant (<0.05), second will show positively insignificant (>0.05) and third will show negatively significant (<0.05) correlation. Can anyone help me in this regard ?
