How can I find the Difference between the Min and Max of all matching cells over different matrices?

Basically I have 12 matrices each for a month of the year (33x45). For each cell I want to know the difference between the max and min values recorded for the entire year.
I then want an output that is another matrix with the resulting differences in the appropriate cells.
Thanks in advance for any assistance :)

so do this
Data(:,:,1)=Month1_Data;
Data(:,:,2)=Month2_Data;
.
.
.
Data(:,:,12)=Month12_Data;
then
Amplitude=max(Data,[],3)-min(Data,[],3);
Amplitude would be what you are asking.

I would put the 12 matrices in a 33x45x12 matrix.
Then you can simply call
max(x,3)-min(x,3)
the '3' refers to take the maximum along the 3rd dimension of x.

Hi, Thanks for your answer. It sort of worked and sort of didn't. This solution gave me another 33x45x12 matrix, where I only want a 33x45 matrix output E.g. so 1:1 shows the max-min of all 12 1:1 cells in the martix...
