I have a structure containing multiple fields of size 1XN and 3XN. I'm looking for a simple way to extract partial data, e.g. the new structure will contain the same fields as the original, but of sizes 1XN-x and 3XN-x.

Thanks.

在 MATLAB Online 中打开

>> S.A = 0:3;
>> S.B = 4:9
S =
  scalar structure containing the fields:
    A =
       0   1   2   3
    B =
       4   5   6   7   8   9
>> x = 2;
>> Z = structfun(@(v)v(:,1:end-x),S,'UniformOutput',false)
Z =
  scalar structure containing the fields:
    A =
       0   1
    B =
       4   5   6   7
