I have a 3D matlab matrix mamed "P3D", row*column*page=64*153*4096. I want to split it into 2D matrix according to the page. I want to get 2D matrix, row*colume=64*153 and the total number of these 2D matrix is 4096. Let's say they are "P2Di" , i=1 to 4096. Also I want to save the 2D matrix into the format of .csv and finally get 4096 .csv files. How could I do this in matlab? Thank you.

I am a beginner with matlab.
