- You can use ismember + indexing to do your task: [idx1,idx2] = ismember(A(:,1:end-1), B(:,1:end-1), 'rows'); idx3 = ~ismember(B(:,1:end-1), A(:,1:end-1), 'rows'); C(idx1,:) = [A(idx1,:) B(idx2(idx1),end)]; C(~idx1,:) = [A(~idx1,:) zeros(sum(~idx1),1)]; C=[C;B(idx3,1:end-1) zeros(sum(idx3),1) B(idx3,end)];

MATLAB has many functions that help create matrices with certain values or a particular structure. For example, the zeros and ones functions create matrices of all zeros or all ones. The first and second arguments of these functions are the number of rows and number of columns of the matrix, respectively.
Jan 3, 2018 · How can I combine 2 matrices A, B into one so that the new matrix C = row 1 of A, followed by row 1 of B, then row 2 of A, row 2 of B, row 3 of A, row 3 of B, etc? Preferably without a for loop? ex: A = [1 2 3; 4 5 6], B = [5 5 5; 8 8 8].
Description. C = cat(dim,A,B) concatenates B to the end of A along dimension dim when A and B have compatible sizes (the lengths of the dimensions match except for the operating dimension dim). example. C = cat(dim,A1,A2,…,An) concatenates A1, A2, … , An along dimension dim.
Mar 2, 2021 · I want to combine them into one final matrix such as all first rows from individual matrices are in first 50 rows and then all 2nd rows and so on. Also, for each set of rows it should insert a header row at the beginning.
Matrix concatenation in MATLAB involves combining or merging two matrices. This process allows for the expansion of matrix dimensions and facilitates diverse data manipulations. In MATLAB, we can concatenate two matrices in several ways, including the following:
Jan 24, 2016 · I need to combine multiple matrices (doubles) (all the same length with padding of 0) into one matrix without losing their 'position'. The problem is when I do that, it seems that the numbers physically add in the one matrix rather than just become one matrix retaining all of the individual numbers. How would I combine all these matrices ...
