- 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)];

Constructing a Matrix of Data. If you have a specific set of data, you can arrange the elements in a matrix using square brackets. A single row of data has spaces or commas in between the elements, and a semicolon separates the rows. For example, create a single row of four numeric elements.
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].
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).
You can concatenate two matrices to create a larger matrix. The pair of square brackets ' []' is the concatenation operator. MATLAB allows two types of concatenations −. Horizontal concatenation. Vertical concatenation.
Mar 2, 2021 · Answered: Walter Roberson on 2 Mar 2021. I have 50 1111 x 3 size matrics. 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: Horizontal way: It will add the matrix next to the other matrix. It’ll increase ...
