How to convert fields in a struct into an int?

I have a struct with 48 fields each 1X128 int32 in it.

I want to combine all the fields into a single 48X128 int32, how do I accomplish it?

Your question is inconsistent. The title states "How to convert fields in a struct into a double?", but then in the description you specify that you want a "a single 48X128 int32". So which is correct: do you want a double or an int32 array?

My Bad!

I want an int32 of dimensions 48X128.

This would be much easier if your data were better designed, exactly as I recommended in your last question (which you have so far not responded to):

The data design means more steps are required. For example, where S is your 1x1 structure:

C = struct2cell(S);
M = vertcat(C{:})

I am getting the following erro when I run the code:-

Error using vertcat

Dimensions of arrays being concatenated are not consistent.

"Dimensions of arrays being concatenated are not consistent."

Indeed, we can see that some of the arrays (e.g. 42, 43, 44) have size 1x129, not size 1x128 as you described.

Clearly they have incompatiable sizes and cannot be concatenated together vertically.
