Thread Subject: extract array from multi-dimensional array

Hi,

I have a 4-D matlab variable called data; size(data)= 192 94 1 1464; ndims(data)=4;
When I write whos in matlab, data is described as 4-D size variable;

I want to extract all the values for data(12,15,1,:), and when I write in matlab:

datum=data(12,15,1,:); datum is also described as a 4-D size array, why is this happening? Shouldn't I get a single-dimension array? i.e. size(datum)=1 1464??

If I'm doing something wrong, could you please tell how can I extract these values from data?

Could you please help me, this issue is driving me crazy!!
Thank you so much to every body,
Best regards,
Jose

It's 4-D because the largest dimension with size greater than 1 is the fourth. (I think it will be size [1 1 1 1464], but you can check to make sure.) Use the squeeze function to collapse it to a size [1464 1] vector.
