Hi,

Please could anyone help me to save A1, A2 and A5 (which are 2D matrices) in a single matrix, and B1, B2 and B5 in another? I have tried with tableA(i,:) = [A1 A2 A5] but it tells me that Dimensions of matrices being concatenated are not consistent. Many thanks

p0 = 1;
p1 = floor(sizedata/5);
p5 = sizedata;
for i = 1:101
    data = squeeze(fulldata(:,i,:));
      A1 = data(p0:p4,:);
      B1 = data(p4+1:end,:);
      A5 = data(p1+1:end,:);
      B5 = data(p0:p1,:);
      A2 = [data(p0:p3,:); data(p4+1:p5,:)];
      B2 = data(p3+1:p4,:);
end

What are sizes of A1, A2 and A5? You need to look into horzcat and vertcat..

在 MATLAB Online 中打开

The shown code cannot work:

A1 = data(p0:p4,:);
A2 = [data(p0:p3,:); data(p4+1:p5,:)];
A5 = data(p1+1:end,:);
tableA(i,:) = [A1 A2 A5]

A1 has p4-p0+1 rows, A2 has p3-p0+1 + p5-p4 rows, A5 has size(A, 1)-p1 rows. It is unlikely that these are the same numbers, please check this. If the number of rows are different, a horizontal concatenation is impossible: [A1 A2 A5].
Even if this work, assigning it to the single row tableA(i,:) would fail, because you cannot assign a matrix to a vector.

Currently the readers cannot guess the intention of the code. Therefore you have to use the debugger at first: Go through the program line by line by setting breakpoints. Now find out what you want to achieve and how the arrays should be joined.
